Mathematical dialplan function
Yeah, I thought it was a little insane too..
adds:
Sum, Multiply, Divide, Subtract, Modulus, GT, LT, GTE, LTE, EQ functions to asterisk
Sum, Multiply, Divide, Subtract, Modulus, GT, LT, GTE, LTE, EQ functions to Asterisk
All functions follow the same basic pattern for parameters:
parameter 1 = the name of the return variable
parameter 2 = the operation
parameter 3 = the second number
parameter 1 = the math expression
parameter 2 = the type of result
Each action is perfromed as
Perform calculation on number 1 to number 2. Valid ops are:
+,-,/,*,%,<,>,>=,<=,==
and behave as their C equivalents.
<type_of_result> - wanted type of result:
f, float - float(default)
i, int - integer,
h, hex - hex,
c, char - char
Each math expression is performed as
Action param1 on param2
