Apparently the overhead for calling a function is high enough that getMin runs far slower than its direct equivalent.
==>%r=getRealTime();for(%i=0;%i<999999;%i++)%d=getMin(getRandom(),getRandom());echo(vectorDist(getRealTime(),%r));

None of my scripts should ever be trying to call getMin 999,999 times per seven seconds, so it's not that large of an issue - I just found it interesting.
Also I feel like there should be a seperate forum for coding discussion that's not actually for help or for mods, which is apparently what this thread is now about.
