#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 :)
