Bases: builtins.float

Format code ‘r’ for scaled output.

__init__(*args, **kwargs)

Methods

__init__(*args, **kwargs)
as_integer_ratio(/)	Return integer ratio.
conjugate(/)	Return self, the complex conjugate of any float.
fromhex(string, /)	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.

Attributes

imag	the imaginary part of a complex number
real	the real part of a complex number
scale	Returns the scale.
scale_val	Returns the scale value which can be used to devide the actual value

__format__(fmt)

Fromats the string using format fmt.

r for scaled output.

Parameters:

fmtstr

format string

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(/)

Return self, the complex conjugate of any float.

fromhex(string, /)

Create a floating-point number from a hexadecimal string.

>>> float.fromhex('0x1.ffffp10')
2047.984375
>>> float.fromhex('-0x1p-1074')
-5e-324

hex(/)

Return a hexadecimal representation of a floating-point number.

>>> (-0.1).hex()
'-0x1.999999999999ap-4'
>>> 3.14159.hex()
'0x1.921f9f01b866ep+1'

imag

the imaginary part of a complex number

is_integer(/)

Return True if the float is an integer.

real

the real part of a complex number

property scale

Returns the scale. (No prefix if 0)

property scale_val

Returns the scale value which can be used to devide the actual value
