Subject: func_math: Return integer instead of float if possible
X-Git-Tag: 18.7.0-rc1~34
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c52ef4ac79b9466af5cf7b17dcc2b9fa2d2badef;p=thirdparty%2Fasterisk.git

func_math: Return integer instead of float if possible

The MIN, MAX, and ABS functions all support float
arguments, but currently return floats even if the
arguments are all integers and the response is
a whole number, in which case the user is likely
expecting an integer. This casts the float to an integer
before printing into the response buffer if possible.
