changelog_0_9_3.md

v0.9.3 - 2024-09-30

Breaks

• PyComplex[T] -> PyTComplex[T]; PyComplex is now non-generics (like CPython's Py_complex)

Bug fixes

• Lib/pathlib: argument order of Path.{sym,hard}link_to was reversed
• os.utime not compile on x86_64 macos

math

• expm1, log1p was inaccurate for arg near 0
• dist's signature was wrong ( used to be func [F: SomeFloat](x, y: F): F )
• degrees was typed as degress
• log1p, expm1 not accurate for arg near 0;

Fixes for inconsistence with Python

• math.{floor,ceil,trunc} now return int over float
• str for complex(N, nan) was "(Nnanj)" (shall be "nanj") and str(complex) returns something in form of Complex(re: A, im: B)
• Lib/math's functions raises exception as Python does when math error occurs
• Lib/math:
  • dist's signature wrongly used that of hypot
  • degrees was typed as degress

Feature additions

• pow for complex type

math

• supports objc (not test yet)

• supports compiletime (nimvm)

• for JS:

  • math
    • gamma, lgamma, erf, erfc are supported
    • ldexp is more accurate

• math:

  • cbrt
  • sumprod, dist, hypot
  • nextafter, ulp
  • ... (all APIs in CPython's math)

• pathlib:

  • /= for Path

Patches for Nim-compatibility
