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, |

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
).
