This release focuses on support for units, but also adds a large number of other fixes and improvements. New features: * Power-off message indicating low-battery situation (#521) * Add `ConvertToUnixPrefix` command and SI prefix menu keys (#513) * Recognize all units that exist in the HP48, and a few more (#491) * `UFACT` (`FactorUnit`) command (#512) * Unit simplification, e.g. turn `1_m^2*s/s/m` into `1_m` (#506) * Converting unity units to numbers (#502) * `→Unit` command (#501) * `UnitValue` (`UVAL`) command (#493) * Implement "kibibytes" (`KiB`) and power-of-two SI prefixes (#492) * Unit arithmetic (#481) * Add `B->R` and `R->B` to `BasesMenu` (#488) * Implement term reordering capability in `rewrite` (#484) * `BaseUnits` (`UBase`) command (#483) * Unit parsing for complex units, e.g. `1_cm^2` (#482) * Unit arithmetic (#481) including automatic conversions (#480) * `Convert` command (#480) * Implement the `Cycle` command for unit objects * Add `Å` character for angstroem (#477) * Add `Merge state` to `State` system menu (#475) * Use Unicode font to display the name of a program when executing it (#469) * Allow incremental search to find digits and Unicode (#468) * Add tool glyph to user interface font Bug fixes: * Do not parse symbols beyond input buffer (#524) * Parse unit menu entries as expressions, not symbols (#523) * Fix reduced-precision arithmetic (#521) * Do not parse empty denominator as zero, e.g. `2/s` (#520) * Do not parse a fraction inside a power, e.g. `X^2/3` (#519) * Convert fractions to decimal in numeric mode (#516) * Do not emit `mantissa_error` for valid numbers (#515) * Apply negation correctly on unit objects (#500) * Do not emit separator after trailing 0 in integer decimals (#489) * Do not emit extra spacing before decimal separator (#485) * Fix stack depth in one error case of `evaluate_function()` * Fix display of next/previous icons for large menus (#478) * Clear settings when loading a state (#474) * Fix separators in whole part of decimal numbers when setting is not 3 (#464) * Parse `(sin x)²+(cos x)²` correctly, as well as HP67 Mach example (#427) Improvements: * Rename `equation` as `expression` (#518) and `labelText` as `label_text` * Do not update `LastArg` except for command line (#511) * ToolsMenu: Connect units to the `UnitsConversionMenu` (#514) * Display unit using `/` and `·`, e.g. `1_m·s^2/A` (#507) * Show units menu for inverse units as `mm⁻¹` (#503) * Display battery level more accurately, i.e. consider 2.6V "low" (#476) * No longer acccept empty equations or parentheses, e.g. `1+()` (#487) * Make `StandardDisplay` mode obey `MinimumSignificantDigits` (#462) * Add algebraic evaluation function for easier evaluation in C++ code * Reimplement `unit` type as a derivative of `complex` (#471) * documentation: Use `🟨` and `🟦` for more commands (#467) * Swap `Search` and `Copy` commands in `EditorMenu` (#466) * `STO` stores variables at beginning of directory (#462) * documentation: Add quickstart guide, used for video recording * documentation: Add links to YouTube videos * documentation: Add release notes * documentation: Some typos and other improvements * documentation: Rework section on keyboard mappings Signed-off-by: Christophe de Dinechin <christophe@dinechin.org> |
