pydicom.valuerep.DSfloat#
- class pydicom.valuerep.DSfloat(val: None | str | int | float | Decimal, auto_format: bool = False, validation_mode: int | None = None)[source]#
Store value for an element with VR DS as
float
.If constructed from an empty string, return the empty string, not an instance of this class.
- Parameters:
- __init__(val: str | int | float | Decimal, auto_format: bool = False, validation_mode: int | None = None) None [source]#
Store the original string if one given, for exact write-out of same value later.
Methods
__init__
(val[, auto_format, validation_mode])Store the original string if one given, for exact write-out of same value later.
Return integer ratio.
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.
Return True if the float is an integer.
Attributes
- 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.
- classmethod 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
