NAME
       clamp - constrain a value to lie between two further values

DECLARATION
       genType clamp(genType x, genType minVal, genType maxVal);

       genType clamp(genType x, float minVal, float maxVal);

       genDType clamp(genDType x, genDType minVal, genDType maxVal);

       genDType clamp(genDType x, double minVal, double maxVal);

       genIType clamp(genIType x, genIType minVal, genIType maxVal);

       genIType clamp(genIType x, int minVal, int maxVal);

       genUType clamp(genUType x, genUType minVal, genUType maxVal);

       genUType clamp(genUType x, uint minVal, uint maxVal);

PARAMETERS
       x
           Specify the value to constrain.

       minVal
           Specify the lower end of the range into which to constrain x.

       maxVal
           Specify the upper end of the range into which to constrain x.

DESCRIPTION
       clamp returns the value of x constrained to the range minVal to maxVal.
       The returned value is computed as min()(max()(x, minVal), maxVal).
