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
