Computed Assignment Operators

u opx

We use y ( z ) to refer to the value of u before (after) the operation. This operation sets z equal to
y op x

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

The following table lists the possible types for x and y (the value of u before the operation) and the corresponding z (the value of u after the operation).
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.
