Release v0.6.2 "Kephas": Restoring the test suite

[c3d]

The focus of this release was to complete the transition to the variable-precision decimal code. The full regression test suite was
restored, with only two tests still failing (complex asin and asinh). The two missing functions, Gamma and LogGamma, were implemented. This also exposed many bugs that were fixed.

New features:

• NumberedVariables setting to allow 0 STO to ease RPN transcoding (Add NumberedVariables mode #690)
• ClearStack (CLEAR) command
• Variable-precision gamma and lgamma functions (Implement decimal gamma function #710)

Bug fixes:

• Do not leave bad expression on stack after error (Addition leaves bad result after Inconsistent units #663)
• Reject unit conversion between undefined units (Adding 1_hms and 1_dms does not error out #664)
• Accept names of menus on the command line (Menus no longer parse correctly #669)
• tests: CLEAR clears stack and errors (Process the CLEAR key in simulator #672)
• The : characters now starts a tag on empty command line (Starting line with : should insert two colons #673)
• Do not evaluate tagged objects too early (Tagged objects no longer remain tagged #674)
• test: Entry and editing of equations (Update test for fancy equation rendering #677)
• test: type returns negative values in "detailed" mode (Add test for TYPE command compatibility mode #678)
• Run loop end pointer not GC-adjusted for last allocated object (Corrupt objects running test suite #679)
• Do not erase alpha indicator when clearing busy cursor (Alpha indicator update running test suite #680)
• Do not emit trailing space when rounding 1.999 to 2. (Trailing space at end of 2. #687)
• Allow expression rewrites to deal with pow (Assertion failed while running expand test #694)
• Reject « character in symbols and commands (Program separators are incorrectly allowed in names #695)
• Rendering of spacing for decimal numbers (Decimal values display differently in equations #699)
• Improve precision of atan function
• Rendering of + and - operators in compatibility modes (Operators display incorrectly in lowercase mode #700)
• Rounding of decimal numbers no longer generates bad characters (Recorder %t format gives wrong result for decimal values #702)
• No longer error out rendering symbolic complex (Bad argument type displaying symbolic complex #703)
• Parse complex numbers correctly inside equations (Unterminated error for '1+2i' #704)
• Ensure sqrt(-1) has a zero real part (sqrt(1) is not exactly 1 #705)
• Do not drop last digit of decimal subtraction (decimal: Incorrect subtraction result #706)
• Evaluate expressions during expression pattern matching (expand and rewrite do not work if typed out #708)
• LastMenu executes immediately while editing (Last menu key should be immediate #711)
• Add back missing angle glyphs in font (Restore missing glyphs in font #712)
• Return correct angle quadrant for atan2 (The atan2 function returns wrong quadrant #715)
• Get no longer rejects arrays as index values (Incorrect error from Get #718)
• Get returns correct error for bad argument types (Incorrect error from Get #718)

Improvements:

• Update .gitignore entry
• Automated testing of setting flags (Repair / Cleanup / update test suite #657)
• Automated testing of non-flag settings (Automatically generate tests for settings #670)
• Test fixed-base based numbers using HP-compatible lowercase notation (Incorrect test for binary and decimal #675)
• Test fraction rendering using fancy digits (Update tests to use fancy fractions #676)
• Add test for "compatible" variant of type command (Add test for TYPE command compatibility mode #678)
• test: Recover from error during data entry (Test suite ends being stuck in symbolic complex addition #681)
• Increase default MaxNumberBits to 4096 (Test of 100! fails because it exceeeds default MaxNumberBitsa #686)
• tests: Add test for cube root of -8 (Add test for cube root of -8 #685)
• tests: Data entry for Σ, ∏ and ∆ (tests: Add keyboard translations for Σ, ∏ and ∆ characters #689)
• Restrict STO to names, natural numbers and specific IDs (Restrict STO and RCL to sensible special names #688)
• doc: Document flas file access for STO and RCL (Document flash storage #691)
• list: Optimize iterators to avoid copies (Optimize iterator comparisons #692)
• tests: spacing-independent testing of structure rendering (Tests should not be too sensitive about exact spacing. #693)
• tests: adjust test suite for variable-precision decimals (Adjust tests for variable-precision arithmetic #696)
• tests: Automatically exit if -T option is given (Automatically exit at end of test suite when running with -T #697)
• tests: Check we don't accept . as meaning 0. for RPL compatibility
• Add modulus alias back for abs (Missing alias for modulus #707)
• Improve convergence speed and accuracy for logarithms
• Add decimal::make to minimize risk of sign errors
• Display stack level at top of stack level, not bottom (Stack level should show at top of stack #709)
• Improve complex sqrt accuracy on real axis (Improve complex sqrt for negative real axis #714)
• tests: Test decimal functions at full 34 digits precision (Validate the various decimal functions at full precision #716)
• Complex sqrt and cbrt with full precision (Compute square root with enhanced precision #717)
• tests: Take into account additional expression simplifications
