#clamp

constrain a value to lie between two further values

#Declaration

• float clamp(float x, float minVal, float maxVal)
• vec2 clamp(vec2 x, vec2 minVal, vec2 maxVal)
• vec3 clamp(vec3 x, vec3 minVal, vec3 maxVal)
• vec4 clamp(vec4 x, vec4 minVal, vec4 maxVal)
• vec2 clamp(vec2 x, float minVal, float maxVal)
• vec3 clamp(vec3 x, float minVal, float maxVal)
• vec4 clamp(vec4 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). The result is undefined if minVal ≥ maxVal.
