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);
- genType clamp(genType x, float minVal, float 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).
