Kinda

About

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

Installation

Kinda is available as a package.

pip install kinda

Comparison

Equality

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

Tolerances

All functions take the same arguments and defaults of math.isclose() and make use the native function when available.

The keyword arguments listed below are for reference. Refer to the math module documentation for more detailed information.

• abs_tol: absolute difference (bigger - smaller))
• rel_tol: difference coefficient (bigger * rel_tol)

>>> import kinda
>>> # reduce absolute precision
>>> kinda.eq(0.9999, 1.0001, abs_tol=0.0002)
True
>>> # reduce relative precision to 5%
>>> kinda.eq(1.0000, 1.0500, rel_tol=0.05)
True
>>> # reduce relative precision to 1%
>>> kinda.eq(1.0000, 1.0500, rel_tol=0.01)
False

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]
