sub

Syntax

int sub(int a, int b, int c)

Arguments

Any integer.

Return

The higher value of (a-b) and c.

Description

This function subtracts 'b' from 'a', then compares the result with 'c' and returns the higher of the two values. This function has been retained for compatibility with Filter Factory; the function max(a-b,c) will give the same result and computes faster.

Example

int p = sub(5,1,2); // sets 'p' to 4, because 5-1=4, and 4>2 !
