pydicom.valuerep.DSfloat

class pydicom.valuerep.DSfloat(val: Union[None, str, int, float, decimal.Decimal], auto_format: bool = False)[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
  • val (Union[str, int, float, Decimal]) – Value to store as a DS.

  • auto_format (bool) – If True, automatically format the string representation of this number to ensure it satisfies the constraints in the DICOM standard. Note that this will lead to loss of precision for some numbers.

__init__(val: Union[str, int, float, decimal.Decimal], auto_format: bool = False) None[source]

Store the original string if one given, for exact write-out of same value later.

Methods

__init__(val[, auto_format])

Store the original string if one given, for exact write-out of same value later.

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.
