# pydicom.valuerep.DS

pydicom.valuerep.DS(val: None | str | int | float | Decimal, auto_format: bool = False, validation_mode: int | None = None) → None | str | DSfloat | DSdecimal

  Factory function for creating DS class instances.

  Checks for blank string; if so, returns that, else calls `DSfloat` or `DSdecimal` to create the class instance. This avoids overriding `DSfloat.__new__()` (which carries a time penalty for large arrays of DS).

  Similarly the string clean and check can be avoided and `DSfloat` called directly if a string has already been processed.
