Introduction

PlainTools is a Python 3 library designed to introduce new features and fix awkward common interactions present in the Python 3 native ecosystem.

Most functions are prefixed with p (as in pt.plist or pt.pround) to avoid homonyms. The p stands for Plain and are the namesake of this package.

Some simple, yet relevant examples using the Plain Number(pt.pnumber) function are:

>>> import PlainTools as pt

>>> 0.1 * 3
0.30000000000000004

>>> pt.pnumber(0.1 * 3)
0.3 # Deals with float imprecision errors.
؜

>>> 5 / 3
1.6666666666666667

>>> pt.pnumber("5 / 3")
1.666... # '...' present only in string format; The true value is still float(5/3).
؜

>>> 1 / 73
0.0136986301369863

>>> pt.pnumber(1 / 73)
0.013698630136986301369863... # Can detect long chains of repeating decimals!
؜

>>> 0.9999999999999988
0.9999999999999988

>>> pt.pnumber(0.9999999999991234)
0.99999999999912 # No loss of precision up to 14 literal digits.
؜

>>> 0.00000000001 ** 3
9.999999999999999e-34

>>> pt.pnumber(0.00000000001 ** 3)
1e-33 # Corrects scientific-notated float imprecisions as well.
؜

>>> pt.pnumber("math.pi") # A safe variation of 'eval()' is used, as shown below!
