Fractions

Module introducing all the functions used to handle fractions.

frac(*arg: Numeric) → Numeric

Returns a fraction instantiated from the module defined by the FRACTION constant. If more than two numbers are provided, an error is raised.

Parameters:

Numeric – One or two numbers.

Returns:

The fraction.

Return type:

Numeric

str_as_frac(s: str) → Numeric

Converts a string to a fraction instantiated from the module defined by the FRACTION constant.

Parameters:

s (str) – A string representing a number.

Returns:

The fraction.

Return type:

Numeric

FLOAT_FRAC = 'float'

Value of the FRACTION constant when float fractions are to be used.

FRACTION = 'gmpy2'

Constant describing which module to use for computing fractions. It can either be “gmpy2” or “float”. The default is “gmpy2”.

GMPY_FRAC = 'gmpy2'

Value of the FRACTION constant when gumpy2 fractions are to be used.
