3.2.3 2025-April-21

Changes

  • Changes how numpy is handled as an optional dependency. Previously,
    importing a numpy-dependent function, like correlated_values,
    without numpy installed would result in an ImportError at import
    time. Now such a function can be imported but if the user attempts to
    execute it, a NotImplementedError is raised indicating that the
    function can't be used because numpy couldn't be imported.
  • Refactors the implementation for the calculation of the derivatives of
    the power function and improves the corresponding testing.

Adds:

  • Adds a small benchmarking suite to CI to guard against absolute
    performance regressions and accidental breakage of the lazy expansion
    algorithm whichs ensures O(N), rather than O(N^2), scaling complexity
    for operations involving many numbers with uncertainty. Established
    connectivity with codspeed.io<codspeed.io>_ to track benchmarking
    results. (#274)

Fixes:

  • Adds documentation for ufloat_fromstr behavior for strings which do
    not contain uncertainty. (#287)
  • Fixes typos in ufloat_fromstr docstring examples (#285)
  • Fixes readthedocs configuration so that the build passes (#254)
  • Fixes all doctests (#281)
  • Adjusts codecov.io configuration so that minor code coverage changes
    will not result in indications that tests are failing. Rather code
    coverage reports will be purely informational for code reviewers.
    Also fix other minor configuration issues. (#270)
  • Fixes a bug that resulted in a ZeroDivisionError while formatting
    very small numbers with uncertainty (#135)

Deprecates:

  • Certain umath functions and AffineScalarFunc/UFloat methods will
    be removed in a future release. A deprecation warning has been added
    to these functions and methods. The following umath functions are
    marked as deprecated: ceil, copysign, fabs, factorial,
    floor, fmod, frexp, ldexp, modf, trunc. The following
    AffineScalarFunc/UFloat methods are marked as deprecated:
    __floordiv__, __mod__, __abs__, __trunc__, __lt__,
    __le__, __gt__, __ge__.
