A pythonic library for floating point number comparison

Project description

Kinda

About

Kinda is a pythonic library for comparing floating point values with Python operator functions.

Arguments

The implementation and documentation are identical to math.isclose.

Comparisons

Equality

>>> import kinda
>>> # a == b
>>> kinda.eq(1.0000, 1.0000)
True
>>> # a != b (default precision)
>>> kinda.eq(0.9999, 1.0001)
False

Precision

All math.isclose() arguments are accepted in all functions.

  • abs_tol: absolute tolerance (abs(a - b))
  • rel_tol: percentage tolerance (1% = .01)
>>> # reduce absolute precision
>>> kinda.eq(0.9999, 1.0001, abs_tol=0.0002)
True
>>> # precision: 1%
>>> kinda.eq(1.0000, 1.0500, rel_tol=0.01)
False
>>> # precision: 5%
>>> kinda.eq(1.0000, 1.0500, rel_tol=0.05)
True

Inequality

>>> import kinda
>>> [kinda.ne(0.9999, 1.0001), kinda.ne(1.0000, 1.0000)]
[True, False]

Less/Greater Than

>>> import kinda
>>> # [a < b, a > b]
>>> [kinda.lt(1.0000, 1.0001), kinda.gt(1.0001, 1.0000)]
[True, True]

Less/Greater Than or Equal To

>>> import kinda
>>> kinda.le(1.0000, 1.0001) and kinda.ge(1.0000, 1.0001)
[True, False]
>>> kinda.le(1.0000, 1.0000) and kinda.ge(1.0000, 1.0000)
[True, True]
>>> kinda.le(1.0000, 0.9999) and kinda.ge(1.0000, 0.9999)
[False, True]
