Several programming languages and libraries provide functions for fast and vectorized clamping. In Python, the
pandas library offers the Series.clip and DataFrame.clip
methods. The
NumPy library offers the clip function. In the
Wolfram Language, it is implemented as {{code |lang=Mathematica |Clip[x, {minimum, maximum}]}}. In
OpenGL, the glClearColor function takes four GLfloat values which are then 'clamped' to the range [0,1]. One of the many uses of clamping in
computer graphics is the placing of a detail inside a polygon—for example, a bullet hole on a wall. It can also be used with
wrapping to create a variety of effects. In CSS, clamp() can help to implement responsive typography or responsive designs generally. Although spreadsheets like Excel, Open Office Calc, or Google Sheets don't provide a clamping function directly, the same effect can be achieved by using functions like MAX & MIN together, by MEDIAN, or with cell function macros. When attempting to do a clamp where the input is an array, other methods must be used. ==References==
