Like, lets say after doing an attack, the total damage is 55.7, but I want that to mean 56. Could I do that? edit: thanks for moving this actually This post has been edited by Glukom on Sep 27 2009, 01:58 PM -------------------- EVERYBODY WHO READS THIS AND DISLIKES THE DIRECTION OF NEW MFGG i feel your pain :[

ceil() rounds up

floor() rounds down

int() rounds down but also converts the number into an integer which will probably **** stuff up for you

So this would work for decimals, then? Like, it won't round 55 up to 60, but it would round 55.5 up to 56?

yeah just decimals

if you ever needed to round eg 55 to 60 you'd have to do something like:

ceil(55 / 10.0) * 10.0

Might I also mention that up means higher and down means lower

as in:

floor(5.4) = 5
floor(-5.4) = -6
ceil(5.4) = 6
ceil(-5.4) = -5

yeah then well:

floor() rounds towards negative infinity and ceil() rounds towards positive infinity

also i was slightly inaccurate with int(); it just chops the fractional part off. so when working with negatives it isn't the same as floor(), it's the same as ceil() (apart from converting it to a true integer), so int() rounds towards 0

translation:

int() truncates

its the correct form of to.........lemme run it down for ya

to is used when your talking about the number. good way to remember this: to has to letters

too is used when your talkin about actions in stuff.

two is used when your talking about places and locations

MMF2 is a piece of **** and has no quick exponent operator

use one of the math extensions and use their raise a number to a power function

For future reference, no languages do unless they're the crappy kind.

^ is almost always XOR, which is a logic operator for exclusive or:
true ^ true = false
true ^ false = true
false ^ true = true
false ^ false = false
