DIM

The DIM function calculates the positive difference of the instantaneous values of two expressions a1 and a2.

DIM(a1,a2) = 0 if a1 < a2

DIM(a1,a2) =a1-a2 if a1 > a2

Format

DIM(a1,a2)

Arguments

 
a1
Any valid function expression.
a2
Any valid function expression.
 
Caution:  
DIM is a discontinuous function and must be used with caution.
