1.1.0

What's new in 1.1

• Functions
• Constants and units
• Input
• Results
• Sessions and settings
• Appearance and panels
• Keypad
• Other improvements

Functions

• Add root(n; x) for nth roots, including negative values and quantities with units. For example, root(5; -32) returns -2.
• Fix factorials in user-defined functions, such as f(n) = n!.

Constants and units

• Search constants by name or unit with Ctrl+Space. Select a result with the arrow keys and insert it with Enter, Tab, or a click.
• Improve searching and keyboard selection in the Constants panel.
• Correct the units of the muon, proton, and neutron energy equivalents.
• Allow powers of grouped quantities, such as (2[m])^2.
• Correct results shown in J/m² and J/m³ when using prefixed units.

Input

• Fix undo and redo, and copy and paste.
• Fix clipped text and excess space in wrapped input with different fonts.
• Fix crashes when typing operators in long, wrapped expressions.
• Restore digit grouping while typing, following the selected number format.
• Add an option to turn off automatic input adjustments, such as operator replacements and closing brackets.
• Add optional Enter-to-accept autocomplete and Escape-to-clear behavior.
• Add an option to use a steady cursor instead of a blinking one.
• Preserve comments as written and prevent them from affecting result formatting.
• Improve recalling expressions from history and focus the editor after startup.
• Remove the empty-history hint.

Results

• Restore free copying.
• Copy a whole calculation, including all displayed result formats, either across multiple lines or as a single line.
• Add optional removal of trailing decimal zeroes.
• Simplify live previews to show just the results.
• Keep live result previews above the editor when recalling long expressions from history.
• Avoid unnecessary extra simplification lines.
• Restore the F2-F5 and F7-F10 notation shortcuts.

Sessions and settings

• Add private tabs that discard their contents when closed and are not restored on the next launch. Use Ctrl+Shift+N (Cmd+Shift+N on macOS) to open one.
• Allow switching between private and saved sessions, and optionally open a private tab at startup.
• Add Reset All Settings..., keeping sessions, history, and user definitions.
• Fix global user definitions missing from restored sessions.
• Make session renaming, cloning, closed-tab recovery, and pane controls easier to find in the menus. Cloning also copies unfinished input.
• Organize the result context menu into Copy, Remove, Split, and Session groups.
• Move Number Format... directly under Settings and simplify the result and appearance menus.
• Apply font changes across all windows and fix font selection on macOS 27 and later.
• Fix commands acting on the wrong window when used from a floating panel.

Appearance and panels

• Add separate system and SpeedCrunch theme choices for menus, panels, and the status bar.
• Add a compact Classic layout for input and results. Modern remains the default.
• Improve text contrast, menu readability, and panel button visibility.
• Match menu icons to the theme and dim disabled menu items and shortcuts.
• Tidy panel spacing, borders, and rounded corners.
• Keep side panels at full height and remember table column order.
• Preserve floating panel positions and visibility across restarts, and prevent floating panels from being grouped unexpectedly.

Keypad

• Add a compact Classic keypad appearance and 50% zoom.
• Restore Zoom in the keypad's right-click menu and fix inconsistent sizing when changing zoom levels.
• Update scientific layouts with nth-root, square, and argument-separator buttons, and group related operations together.
• Replace the obsolete lg button with log10.

Other improvements

• Reduce startup delays when restoring sessions, history, and panels.
• Make update checks more responsive and prevent them from delaying window closure.
• Add Help > App Diagnostics with a report that can be copied when asking for help. Show operating system details in About SpeedCrunch.
• Fix a crash when closing windows with certain panels open.
• Add portable macOS ZIP packages that keep settings and sessions beside the app in a SpeedCrunch-data folder.
• Set the default macOS minimum version to 14.4 on Apple Silicon.

1.0.0

What's new in 1.0

• Workspace and history
• Expressions and editing
• Results and formatting
• New functions
• Units
• Appearance and settings

Workspace and history

• Work in tabs and split panes to keep several calculations open side by side.
• Save calculation history between launches and set a history size limit.
• Load your own functions and variables at startup.
• Choose a keypad preset or build a custom keypad.
• Show or hide the main menu. The result display now has a right-click context menu with an entry for the main menu.
• Re-edit an earlier expression and recalculate all the expressions below it.
• Check for updates from within the app.

Expressions and editing

• Use lists and matrices in expressions.
• See the interpreted expression alongside the result, with implicit multiplication made explicit.
• Write integer powers with superscript digits.
• Use √, ∛, Σ (summation), and π as aliases. The ~ operator is an alias for not().
• More symbol aliases are accepted for addition, subtraction, multiplication, and division.
• Autocomplete suggestions now show category icons.
• Pasted numbers are automatically formatted to match the global Number Format setting.
• Insert constants and formula book entries with their units included.

Results and formatting

• Show a calculation in several result formats at once. Number-format choices include Indian 3-2-2 digit grouping.
• Show rational results as fractions, or use sexagesimal notation for angles and time.
• Show angles as multiples of pi in radian mode or through an explicit conversion.
• Choose how complex numbers are displayed, with polar forms and options for the imaginary unit.
• Set a custom precision with the Custom... option.
• Choose from five rounding modes.
• Changing the primary result format updates only the last expression. Earlier history entries keep their formatting.

New functions

• Integer arithmetic: powmod for modular exponentiation, emod for Euclidean modulo, lcm for least common multiples, and popcount for counting set bits.
• Number formatting: binpad, octpad, and hexpad for padded binary, octal, and hexadecimal output. Use sci and eng for scientific and engineering notation.
• Random numbers: rand and randint generate random decimals and integers.
• Dates and time: datetime and epoch convert between date/time values and Unix timestamps.
• Summation: sigma, also written as Σ.
• Complex numbers: conj for complex conjugates and cis for constructing a complex number from an angle. Choose rectangular, exponential, or phasor output with rectform, expform, and phasorform.
• IEEE 754: ieee754_round_* rounds to a floating-point format, and ieee754_*_residual(x) returns the rounding residual. Both families support half, float, double, and quad.
• Chemistry: molmass, mass, and molarity for molar mass, mass from an amount of substance, and solution molarity.
• Linear algebra and data: List and matrix support with cols, corrp, corrs, covp, covs, cross, det, dot, flatten, inv, norm, rank, rows, shape, trace, and transpose.
• Statistics: stdevp, stdevs, varp, vars, and mad, with list and matrix support.

Units

Use square brackets to identify units explicitly in expressions, such as [m] or [s]. New units and aliases include:

• Angles: gradian (gon), turn (tr, pla), revolution (rev), degree (°), arcmin (′), and arcsec (″).
• Time: Julian century (cy_jul).
• Area and mass: hectare and tonne.
• Speed: kph and mph.
• Energy: quad, equal to 10¹⁵ [Btu].

Appearance and settings

• Choose from more built-in themes or create a custom theme.
• Interface scaling now applies to the expression editor too.
