I've set up some HP gauges and such for my MUD, and they seemed to be working normally for a while, but now they've got this weird problem.

There's a 'wimpy' feature on my MUD, and you set it to a % of your total HP. I want my gauge to change color when it gets to that % so I set up the gauge like this:

Gauge value: @HP
Gauge max: @HPmax
Gauge low: (@HPmax/100)*15

Both those variables are captured from triggers, and their values capture correctly, but I've discovered my gauge doesn't change colors until it is at least 3 below the value that the math should give it.

For example, I have 519 HP on the MUD, and a wimpy of 15, so the gauge should turn red at 77.225% or something like that, which I assume would be rounded to 77. The gauge won't change colors until it's at 74HP or lower, though.

I tried this with a couple other amounts (went up to 16% and down to 14%), and it had the same effect: the gauge actually changed color 3 lower than the math said it should.

I always updated my variables and they were at the correct values, and there are no #MATH triggers that are messing with those variables at all, so I can't figure out what the problem is.

zMUD uses integer math, so you'll seldom get exact numbers. However, you'll get closer if you do the multiplication first instead of the division.
@HPmax = 519
(@HPmax/100)*15 = (519/100)*15 = 5*15 = 75
(@HPmax*15)/100 = (519*15)/100 = 7785/100 = 77

Thanks a bunch, that seems to have fixed it (it's still 1 below the 'low number' but I assume that is by design). I never even thought of doing it the other way around... Math isn't exactly my strong suit ;)
