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).
