#declare noWrap=function(x) {max(min(x,1),0)}
//now you can do things like:
#declare repeatingFunction=function {x}
#declare nonRepeatingFunction=function{noWrap(repeatingFunction(x))}
//or, very usefull with pigment functions:
#declare troublesomeFunction=function {pigment {image_map {png
"yourpng.png" interpolate 2}}}
#declare
notSoTroublesomeFunction_Red=function{noWrap(troublesomeFunction(x,y,z).red)}
Hope this helps! Don't really know what you mean by "dividing the
function's power" though, so maybe this is of no use at all to you :)
