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
|
|
|
|
All functions follow the same basic pattern for parameters:
|
|
|
|
parameter 1 = the math expression
|
|
parameter 2 = the type of result
|
|
|
|
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
|
|
|
|
eg:
|
|
|
|
Action = Divide
|
|
Param1 = 10
|
|
Param2 = 2
|
|
|
|
Results in
|
|
|
|
Divide 10 by 2
|
|
|
|
|
|
Example dialplan:
|
|
|
|
exten => 11099,1,Set(RV=${MATH(1+20)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(10*2)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(10*2)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(10-2)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(2%10)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(10/0)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(10-200)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(1-20)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(1<20)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(1>=20)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(101>20)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(1==20)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(20<=20)})
|
|
exten => 11099,n,NOOP(${RV})
|
|
exten => 11099,n,Set(RV=${MATH(123%16,int)})
|
