3.2.3

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__.
