numpy.min_scalar_type¶
- numpy.min_scalar_type(a)¶
For scalar a, returns the data type with the smallest size and smallest scalar kind which can hold its value. For non-scalar array a, 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.
