#IF and numbers with a decimal point not working right
 
I feel like i should know this already....

Code:

#ALIAS SRTest2 {
 #IF (@SRNightCTemp <= @SRIslandTemp) {
   #VARIABLE SRPurchase NightClub
   #VARIABLE SRLowestTemp @SRNightCTemp
   #ADD SRTotalCost @SRNightCCost
 } {
   #VARIABLE SRPurchase Island
   #VARIABLE SRLowestTemp @SRIslandTemp
   #ADD SRTotalCost @SRIslandcost
 }
 #ECHO @SRPurchase - @addcommas( @SRTotalCost),000 Spent so far
}
#VAR SRIslandTemp {1337.5} {_nodef}
#VAR SRNightCTemp {1075} {_nodef}
#VAR SRIslandCost {2675000} {_nodef}
#VAR SRNightCCost {21500} {_nodef}

Run it and i get:
NightClub - 21,500,000 Spent so far
which is correct.

I decided to check and see if it would work if SRNightCTemp was higher, so i made it 10750, and i still get:
NightClub - 21,500,000 Spent so far

I take out the .5 in the SRIslandTemp and i get:
Island - 2,675,000,000 Spent so far

Why is the .5 throwing it off?

i might think your trying to reference an illegal dbvariable....

"i might" or "IT might" ?
Cause if you do, then tell me why and how.

If IT might...then dang it how do i smack it around?
I can't believe that it can't handle comparing #'s because of a decimal point.

Use the %int function (forces the value to be treated as an integer instead of a string value).

This ties a little into your other question about really large numbers. ZMud stores everything in variables as strings, which essentially means that there's no limit to your variable sizes except to have enough bits in memory to record the actual length of the data (keep in mind that this is me looking in from the outside, so Zugg might have gone with a fancier approach involving Class Objects).

Because everything is in string format, ZMud uses some internal logic to autocast data into the appropriate type needed by each command/function. This logic gets mixed up or doesn't come into play if you work with variables as you are, so you need to force the issue with casting functions like the %int() Charneus suggested. Use %int() if you only want integers, use %float() if you want to retain decimals.

Char:
awesome on the %int()
#IF (%int( @SRNightCTemp) <= %int( @SRIslandTemp))
works perfect!

Matt:
Unsure if you meant that I should do this:

With the 000 added to both cost and gain:
#MATH SRIslandTemp %int(@SRIslandCost)/%int(@SRIslandGain)
Unfortunately, still gave me 1073 Crying or Very sad

As for the %float it's easier on the eyes to put .0 in the Gain variable.
#MATH SRIslandTemp %float(@SRIslandCost)/%float(@SRIslandGain)
#VAR SRNightCGain {20} {_nodef}
is just to busy for me in the math section

#MATH SRNightCTemp @SRNightCCost/@SRNightCGain
#VAR SRNightCGain {20.0} {_nodef}
just looks better to me

Remember, i'm the guy who's eyes watered and nearly burst trying to read cmud code ;-)
