Data type are aranged in a hierarchy. See the DtypeCategory object documentation for more information. Use issubdtype() to determine if one dtype (or category) is a subtype of another category.

Dtype

An object to hold the type of a array.

DtypeCategory(value)

Type to hold categories of dtypes.

issubdtype(arg1, arg2)

Check if a Dtype or DtypeCategory is a subtype of another.
