Pmap
processing
Re-maps a number from one range to another.
In the first example, the number 25 is converted from a value in the range of 0 to 100 into a value that ranges from the left edge of the window (0) to the right edge (width).
As shown in the second example, numbers outside of the range are not clamped to the minimum and maximum parameters values, because out-of-range values are often intentional and useful.
