PyFloat Lib

Python Library for doing math operations with floats without lossing precission

How to use

>> from pyfloat import PyFloat

>> PyFloat(2.1234e-12)
'0.0000000000021234'
>> PyFloat(-2.1234e+12)
'-2123400000000'
>> PyFloat(0.1452)
'0.1452'
>> PyFloat(PyFloat(152.455))
'152.455'
>> a = PyFloat("123451.1234551230000000004444445551122000000011")
>> b = PyFloat(-8123994.000002234100000001323400000001232112221)
>> a + b
'-8000542.8765471111000000008789554448890321122199'
>> a - b
'8247445.1234573571000000017678445551134321122221'
>> a * b
'-1002916186242.9543234169148643344158458369442274183843912848765430855693663896461975553234431'
>> a == b
'False'
>> a != b
'True'
>> a > b

>>> PyFloat(0.00239419391).round(10)

>>> PyFloat(0.00239419391).round(4)
'0.0024'
>>> PyFloat(-1234.5678).abs()
'1234.5678'
>>> PyFloat(0.0000089778).truncate(8)
'0.00000897'
