v1.10.0

What's Changed

• cleanup + fix decimal_debug bugs by @anzdaddy in #83
• further performance improvements by @anzdaddy in #84

Full Changelog: v1.9.0...v1.10.0

v1.9.0

Performance tweaks

• Faster parsing and formatting

v1.8.0: performance fixes (#81)

• Much faster Quo
• New Int64x behaves the same as Int64 but reports whether the conversion was exact.
• ScaleB/ScaleBInt return a * 10^b.
• Precook small integers [-10, 10].
• make profile convenience rule

v1.7.0

• Simpler formatter
• Precalculate 128-bit 10ⁱ

v1.6.0

• improve rounding algo, support half-up rounding
• support context-controlled parsing
• add make lint
• fix formatting regression

v1.5.0

Context64.Rounding is now exported, providing access to alternate rounding strategies.

v1.4.0

• Improve formatting of large and small exponents.
• Add two new methods.
  • Decimal64.Round rounds a number against a reference power of ten.
  • Decimal64.ToIntegral rounds a number to a whole number (equivalent to Round with 1 as the reference).

v1.3.0

Fix formatting issues with extremely large and small numbers when using fixed precision.

v1.2.0

tl;dr: Better testing + more useful methods + debug info + more docs

• Now all dectests in scope are individually wrapped in a t.Run
  • Previously relied on manual inspection of test results
• decimal_debug compiler tag injects helpful debug info to every Decimal64 instance
  • A compiler tag ensures zero cost when not compiled in. Use only for interactive debugging.
• New Decimal64 methods
  • Min/Max/MinMag/MaxMag returns smallest/largest in absolute and magnitude terms
  • Logb returns integral log₁₀ (the exponent, essentially)
  • CopySign combines the value of one number but gives it the ± from another
  • NextPlus/NextMinus returns the nearest neighbor above or below a number
• Add support for output precision (e.g., %.10f) when formatting decimals
  • %g still pending
  • width (%06f) still pending
• Pin go.mod and CI to Go 1.20+
• Upgrade CI actions
• Helpful usage notes in README.md

Breaking change:

• Change Decimal64.MarshalText method signature to conform to encoding.TextMarshaler
  • Breaking change was unavoidable to implement interface
