Allow floating-point division by zero in ZScript

[AFADoomer]

You are correct. I started with a different example, and ended up putting the max in the wrong place when I changed it up...

[argv]

For brevity's sake, I usually end up putting in a "max([divisor that might end up as zero], [arbitrary small number]);" call in cases like this...

e.g.:

Code: Select all

TweenChange = 1. / (max(time, 0.0001) * TICRATE);

Not sure if that slows things down internally any more/less than using if statements to the same effect, but I haven't noticed any issues so far.

Good idea. As Graf confirmed, that's faster than if branches.

I've replaced the if with similar code:

Code: Select all

TweenChange = 1. / (max(time, double.epsilon) * TICRATE);

Thanks for the idea.
