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. - 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)}) exten => 11099,n,NOOP(\${RV})
