Math
cmd Math is deprecated in Asterisk 1.2. use func Math instead
Synopsis
math(returnvar,operation,number)
Description
Adds Sum, Multiply, Divide, Subtract, Modulus, GT, LT, GTE, LTE, EQ functions
All functions follow the same basic pattern for parameters:
- returnvar: the name of the return variable
- operation: the operation
- number: the second number
Each action is performed as
Action param1 on param2
eg:
Action = Divide
Param1 = 10
Param2 = 2
Results in
Divide 10 by 2
