{{alias}}( [dtype1, dtype2] )
|
||
|
|
Returns the ndarray data type with the smallest size and closest "kind" to
|
||
|
|
which ndarray data types can be safely cast.
|
||
|
|
|
||
|
|
If not provided data types, the function returns a type promotion table.
|
||
|
|
|
||
|
|
If a data type to which data types can be safely cast does *not* exist (or
|
||
|
|
is not supported), the function returns `-1`.
|
||
|
|
|
||
|
|
If provided an unrecognized data type, the function returns `null`.
