Methods

__init__()

as_integer_ratio()

Return integer ratio.

conjugate()

Return self, the complex conjugate of any float.

fromhex()

Create a floating-point number from a hexadecimal string.

hex()

Return a hexadecimal representation of a floating-point number.

is_integer()

Return True if the float is an integer.

as_integer_ratio()

Return integer ratio.

Return a pair of integers, whose ratio is exactly equal to the original float and with a positive denominator.

Raise OverflowError on infinities and a ValueError on NaNs.

>>> (10.0).as_integer_ratio()
(10, 1)
>>> (0.0).as_integer_ratio()
(0, 1)
>>> (-.25).as_integer_ratio()
(-1, 4)
conjugate()
