saturate() ???

is there any saturate function in glsl??? there are a lot of examples within this function call, but didn’t find it in the spezification and while compiling my source i get an error … so whats up with it??? any ideas??? thx

Sure you’re looking at glsl examples and not hlsl or cg? either way, a saturate in glsl is ‘res = clamp(value,0.0,1.0);’
