Binary Numeric Operators With an AD Result

z = x op y

Sets z to the result of the binary operation defined by op and with x as the left operand and y as the right operand.

The possible values for op are
op    Meaning
+ addition
- subtraction
* multiplication
/ division
** exponentiation

The following table lists the possible types for x and y and the corresponding result type for z .
x           float    a_float   a2float
-   float    a_float   a2float
-  a_float   a_float
-  a2float             a2float
The type float does not need to be matched exactly but rather as an instance of float.

Either 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).

The file contains an example and test of these operations. The file contains an example and test of the future division operator
