Been gone so long...

Hi!
Scuse me for being gone for so long, but I've been busy in Waisting time. I come with a COG problem...

The question is, why is my INT read as a FLEX?
Code: 
int		rant				local
int		rantt				local

rant=(rand()*5);	rantt=(rant*2)+10;
SetTimerEx(GetSoundLen(ctempo),7,rantt,0);

printflex(GetParam(0));


Result on the print: A full decimal number. 13.364818 etc.

So, what's missing in the equation so I only get even numbers from 10 and up?

Everything gets treated as a float...there's a couple ways to truncate it to an int though, such as:
a = a - a % 1;

Great! Thanks! I now get whole int numbers!

Now, I see there be a problem with my equation, or something else, for I'm also getting the odd numbers. How do I get only the even numbers (10, 12, 14, 16...)

Nevermind... Figured it out... %2!

I'm not completely sure what you want to do, but if you are trying to round numbers to their next even neighbour, then you could truncate the number using Sige's code, and, if the new number is uneven (number % 2 = 1), simply add 1.

To truncate to the nearest (but always less than or equal to) even value, you'd do just what edward said, a = a - a % 2;
To get odd numbers under the same condition you could do a = a - (a - 1) % 2; (I think, haven't tried that :P)

Actually, I think he could just move the truncate code. Try putting the truncation between rant=(rand()*5); and rantt=(rant*2)+10; statements.
