as the right operand.

x
and
y
and the corresponding result type for
z
.

-------------------------------
float - float a_float a2float
a_float - a_float a_float
a2float - a2float a2float
float does not need to be matched exactly
but rather as an instance of float.
x
or
y
or both may be
a numpy.array with elements
that match one of possible type choices above.
If both
x
and
y
are arrays, they must have the same shape.
When either
x
or
y
is an array,
the result
z
is an array with the same shape.
The type of the elements of
z
correspond to the table above
(when the result type is a float,
this only refers to the element types matching as instances).
