numpy.min_scalar_type¶

numpy.min_scalar_type(a)¶

For scalara, returns the data type with the smallest sizeand smallest scalar kind which can hold its value. For non-scalararraya, returns the vector’s dtype unmodified.

Floating point values are not demoted to integers,and complex values are not demoted to floats.

Parameters:	a:scalar or array_like The value whose minimal data type is to be found.
Returns:	out:dtype The minimal data type.
