SumWise 3.2.1 Release Notes

Current Windows Store release

SumWise 3.2.1

Move from a calculation or dataset to a reviewed comparison, saved workspace and selected report. The Store release keeps native algebra, units, matrices and supported 2D/3D graphing alongside the new workflows.

• Describe raw or frequency-entered data and inspect retained numerical tables, histograms, boxplots, ECDF and Normal Q-Q plots.
• Use raw or supplied-summary mean procedures: one-mean t, independent Welch or pooled t, and z with separately supplied known population SD. Interval-only results do not require an invented hypothesis. Paired analysis requires genuine paired rows.
• Compare two to four groups using ordinary or Welch ANOVA and complete pairwise families with Holm-adjusted tests and Bonferroni intervals.
• Inspect supported regression models, residuals and explicit predictions. Exponential and power uncertainty intervals remain unavailable.
• Find a tool by task and keep guidance alongside inputs and results.
• Export supported figures as vector PDF or PNG and selected reports as searchable PDF, alongside existing HTML/text output. 3D remains raster; report figures may be raster. SVG export is unavailable.
• Corrected file activation and numerical edge cases in mean inference and exact binomial testing. The 3.2.1 executable declares Per-Monitor V2 DPI awareness.

Existing results and files

Already-saved numbers stay unchanged on Open. Explicit Review/Run uses current methods; opening does not freshly verify or authenticate old results. Older-only content retains its compatible encoding. Newer record types can require a newer reader; a genuinely incompatible upgrade of a named file requires Save As to a distinct destination. Preserve the original.

The Store package does not include the private Python calculation backend. Supported stored symbolic records remain readable and retainable; that does not enable recalculation through an unavailable engine. Some technical reports/examples remain in English, and numerical input uses the documented decimal-point syntax.

Historical release

SumWise 3.1.0

SumWise 3.1 is available now on Microsoft Store. Four interface languages and six bounded exact Desktop workflows are included in one application.

Four interface languages, bounded localized Ask and report headings, plus six exact Desktop workflows: poly_divrem, poly_gcd, linear_solve_exact, interpolate_exact, rational_simplify and solve_rational.

Keep legacy originals. Adding domain-qualified results requires Save As to a genuinely different file; workspace 6 is rejected by tested older readers. Opening old-only work does not migrate it. Open performs bounded mathematical validation.

SumWise 2.6.0

What's in SumWise 2.6

Calculate with units, compare scenarios, save work and share selected results.

• Supported mechanical/electrical quantities and compatible output units, with canonical reuse separate from rounded display.
• Guided speed, force, kinetic energy, resistor current, steady DC power, RC time constant and capacitor energy relationships. Review Find targets, inputs and assumptions before Prepare, Insert and explicit calculation.
• Two-to-four scenario comparisons on common unit axes. Show/hide curves, pin an approximate coordinate and Generate a common-grid Values table with per-curve statuses and domain gaps. CSV includes hidden curves.
• Save/reopen supported graph and calculation state, including visibility, viewport and an approximate pin. Save As keeps a distinct variation.
• Offline HTML Analysis Reports containing deliberately selected recorded calculations, a supported quantity graph/comparison and optionally a current generated table. PNG, CSV, Markdown and text serve their respective sharing workflows.
• Three Examples walkthroughs, clearer mathematical display, protected draft insertion, improved graph callouts and more responsive report selection with long histories.

Try supported quantities

Copy only the expression, then press Enter.

5[m] + 30[cm]

sqrt(9[m^2])

sqrt(2[m^2])

The square roots give Exact 3 m and an Approx length near 1.41421356237 m respectively. Exact/Approx refer to represented arithmetic, not the certainty of a measurement. Numeric and rational limits still apply; no arbitrary-precision or universal-exactness promise is made.

2.6 workspace and sharing scope

Graph samples, pins and generated tables are approximate. Saved graphs and captured workspace/ans values are snapshots, not automatic dependencies. Guided formulas cover supported idealized relationships, not general word problems or circuit simulation.

Save retains supported state, not every graph or custom-function environment. Uninserted guided fields, report options and generated tables are temporary. Generate Values again after reopening. Reports are selected presentations, not editable workspaces, live calculations or PDF output. Exporting does not mark work saved or retire recovery. Checkpoint recovery and observed external-file checks are not guarantees against every filesystem or power-loss condition.

Historical release · Scientific Workspace

SumWise 2.5.0

Calculate. Preserve. Search. Reuse. Graph. Convert. Share. SumWise 2.5 brings a continuing scientific workspace around the Windows calculator.

Save and revisit your work

• Save, Open, New and Recent .sumwise workspaces.
• A persisted calculation transcript, stored variables, unfinished input and numerical preferences.
• Guarded local recovery for supported unsaved work.
• Search Calculations to find retained records and inspect or reuse earlier work.
• Markdown and text calculation exports for a readable transcript.

Find an operation and reuse a value

• Quick Insert searches functions, constants, examples and current variables without evaluating.
• Live variable autocomplete helps while editing.
• Manage Variables lets you inspect current bindings, copy names or formatted values, insert names and deliberately remove variables while retaining ans.
• A searchable Unit Converter previews compatible conversions and inserts the expression.

Present and share scientific work

• Auto or Scientific notation and 3–15 significant-digit display precision.
• Export Graph as PNG and Copy Graph Image for static plot sharing.
• Improved failed-input correction, clearer common-error guidance and keyboard/workspace usability.

What each file preserves

A saved workspace preserves supported continuing calculation state. A recovery copy is the last successfully committed checkpoint of supported unsaved work, not proof that every current change is saved. Active interactive graphs and custom functions are not persisted in workspace files and can prevent Save or recovery.

Markdown/text exports are readable transcripts, not resumable workspaces. PNG exports are static graph images. Removing current variables does not rewrite historical results. Display precision changes presentation, not arithmetic precision or significant-figure tracking.

Historical release

SumWise 2.4.0

SumWise 2.4.0 is a Windows desktop correctness, reliability, and responsiveness update focused on stronger exact simplification for eligible expressions passed directly to simplify(...).

Stronger Exact Simplification

• Eligible homogeneous same-monomial sums with two through seven physical additive terms can use the strengthened exact behavior.
• Supported signed integer and rational coefficients are combined deterministically.
• Supported positive integral powers and multi-symbol monomials such as y^2 and a*b^3 are preserved.

simplify(2*x + 3*x) -> 5*x

simplify(x + 2*x + 3*x) -> 6*x

simplify(3*x/2 + x/2) -> 2*x

Conservative Compatibility

The new exact behavior applies only when an explicit simplify(expression) input is conservatively eligible. Unsupported or uncertain forms, heterogeneous or mixed terms, nonadjacent repeated groups, cancellation, one-term inputs, and expressions with more than seven physical additive terms continue through the established simplifier.

Inputs with more than seven physical additive terms remain supported rather than being rejected. Existing behavior such as simplify(x - x) -> 0 is preserved, and the update does not route every expression or every simplify(...) input through the new bounded behavior.

Reliability And Responsiveness

Reliability work strengthens deterministic results and conservative fallback for the supported workflow. Two through four eligible homogeneous terms are expected to be responsive. Five eligible terms may produce a noticeable subsecond synchronous calculation, while six or seven may create a brief synchronous wait. Timing depends on the computer and current system load. This release does not add asynchronous evaluation or a progress indicator.

Current Scope

SumWise 2.4 supports practical scientific computation, interactive graphing, exact results, statistics, regression, matrices, vectors, units, and supported symbolic algebra and calculus workflows. It does not claim universal general-purpose CAS coverage or support for every equation type.

Historical release

SumWise 2.3.0

SumWise 2.3 was a Windows desktop update focused on making graphs easier to explore and share while adding the Microsoft Store trial, license, localized-price, and purchase experience for the coordinated 2.3 launch.

Graph Inspection And Interaction

• Hover near a visible plotted curve to inspect its function label and approximate coordinates.
• Click an inspected curve point to keep its coordinate pinned while you continue exploring.
• Copy a pinned coordinate in a compact, reusable text format.
• Hidden functions and discontinuity gaps remain excluded from curve inspection.
• Existing graph pan, wheel zoom, reset, visibility, and overlay behavior remains available.

Graph Copying, Export, And Visible Controls

• Copy the current graph directly as an image.
• Save a clean, high-resolution PNG of the visible graph.
• Use visible controls for zoom in, zoom out, reset, image copying, and PNG saving.
• Graph exports include the current viewport, visible curves, supported overlays, and a persistent pinned point when present.
• Transient hover state and surrounding application controls are excluded from exported graph images.

Microsoft Store Trial And Purchase Experience

• Try every SumWise feature during a full-featured seven-day Microsoft Store trial.
• See calm, clear trial and license status inside the application.
• View the localized price supplied by Microsoft Store where purchase is available.
• Purchase through Microsoft Store and unlock only after the paid entitlement is verified.
• Continue using the verified public scientific, graphing, symbolic, calculus, statistics, matrix, vector, and unit-conversion feature set.
