[MAXScript] Checking if variable is integer or float

Wesley

Hey, stuck on something really simple here. I've got a simple line of code:

if classOf (variable01 - variable02) == integer then
(
     print integer
)
else
(
     print float
)

The problem being that when Max is given two integers it'll always round. If I supply the two variables as floats and it get number.0 then it'll still be a float class.

I must be missing something insanely obvious here, any help would be much appreciated.

You can try using ceil or floor :

variable01=2
variable02=3.2
someVariable=variable01 - variable02
if ((someVariable - floor someVariable) == 0)then
(
     print integer
)
else
(
     print float
)

edit: damn, i did not read what you posted properly

If you are mixing floats with integers you always get float as a result. You can always explicit cast the result to a float or an integer.

The problem though is that when calculating two integers that results in a float, like 999 divided by 6, the 166.5 gets rounded to 166.

I'm wanting the result to instead either be a integer (when it's an integer obviously) or a float (when it's a float).

I should have given this a different title to this.

Is there then a way to then check if the float has numbers other than 0 after the decimal then...

Essentially the user is able to pick any two integers and I need to put a check to make sure they've picked two where one is divisible by the other.

Ah, if I understand you correctly then you want the modulo operator. E.g

if mod v1 v2 == 0 then 
    print Integer
else
    print float

Wesley

That's perfect! I had no idea about this operation or it being in Max, thanks man!

Just beat me to it. :P

For future ref, see "Number Values" in the MaxScript help documents.

Yeah thanks for the tip, lots of awesome methods that I've never discovered before.
