min function

min(X,Y)

Returns lesser of X and Y; i.e. it returns X if X<=Y, otherwise it returns Y.

Inputs: numeric, numeric

Result: numeric

Comments:

The min function is a useful way of ensuring that some value does not go above some threshold. For example, if b increase as a increases, but does not exceed 20, then the equation for b could be:

b = min(20, 0.2*a)

This avoids the use of a cumbersome if…then… else… construction
