The following mathematical operators always convert the values they operate on (operands) to a numeric form. If any operand is a float then the return value will also be a float, otherwise the return value will be an integer. The only exception is division, where the result may be a float as required.
If you need to manually convert between different numeric types, or round floating values, see the section Type Casts.

- |
The second value subtracted from the first. Added in v1.1. |
|
* |
The multiplication of the values. Added in v1.1. |
|
