Release 0.6.4 "Healing": Testing and fixes

[c3d]

This release focuses on heavy testing of the new variable-precision decimal stack. Adding tests also means finding bugs.

Another significant change is support for fixed-precision hardware-accelerated floating point, using 32-bit and 64-bit IEEE754 binary floating-point representation. Since this uses a binary format, some decimal values do not map to decimal correctly. For example, displaying 1.2 with a large number of decimals will show residue, because 1.2 does not have an exact (zero-terminated) representation in binary.

New features:

• plotting: Make refresh rate configurable
• menu: Add / key to FractionsMenu
• hwfp: Add support for hardware-accelerated floating-point
• menus: Add hardware floating-point flag to MathModesMenu
• ui: Allow multiple uses of . to insert DMS separators
• HMS: Editing of HMS values in HMS format

Bug fixes:

• stats: Fix crash on variance with single-column statistics
• algebraic: Clear error before evaluating the function
• functions: Correctly emit a type error for non-algebraics
• ui: Make sure we save stack if closing the editor
• logical: Fix mask for rotate left with 64-bit size
• logical: Make sure we save args for single-argument logicals
• flags: Update flags on FlipFlag, consume them from BinaryToFlags
• stack: Show multi-line objects correctly
• lists: Returns Bad argument value for index with bad arguments
• lists: Return an empty list for tail of empty list
• arithmetic: →Frac should not error on integers
• power: Do not shut down during WAIT if on USB power

Improvements:

• menu: Shorten the labels →QIter and →QPrec to avoid scrolling
• stack: Avoid running same code twice on simulator
• ids: Add aliases for hardware floating point
• functions: Optimize abs and neg
• ui: Replace calls to rt.insert with calls to insert
• menu: Reorganize fractions menu
• dms: Do the DMS conversion using fractions
• list: Adjust multi-line rendering
• copyright: Update copyright to 2024
• text: Return null text when indexing past end of text

Testing:

• tests: Increase the delay for help to draw
• tests: Add tests for hardware-accelerated floating-point
• tests: Add shifts and rotate tests
• tests: Check flag functions
• tests: Test DMS and HMS operations
• tests: Add test for integrate using decimal values
• tests: Test multi-line stack display
• tests: Add tests for GETI
• tests: Min and max commands
• tests: Repair last regression test
• tests: Check behaviour of 0^0
• tests: Avoid string overflow in case of very long message
