Calc for result or zero

I have a calculation that works, but I'm thinking there's probably a more elegant solution:

If( myNumber - 1 > 0, myNumber - 1, 0 )

I.e., I want to subtract one, but not go into negative numbers. Is there a clever-er calc for this?

Max( myNumber-1; 0 )

is a little smaller, you might also save a few microseconds since the subtraction was only done once...

That looks right. I thought I'd looked at Max, but maybe it was Min I thought about and Min won't work. Thanks, Shad.
