Clamp 0 1 Scalar will turn any value above 1 to 1 and any value below 0 to 0, leaving everything in between as is.
Using a cosine signal with a range of +2 to -2 as the heights of the curves peaks...
...we can demonstrate that there is a sharp stop to any values above 1 and below 0.
Clamp 0 1 Scalar is useful when combining multiple scalar sources together, for say a mask, and will prohibit negative or above 1 values interfering with a desired 0 to 1 range.
If there's any errors, omissions or questions about the above, please leave a comment and we will add further details in this post when relevant.
