That's very useful, thanks! I remember I was looking for something that would do that a while ago, but I don't remember exactly what for... but I'll remember that.

my 2 cents...
int(log(#)+1 = How many digits the number is
example
Text(0,0,sub(" 00000000",1,8-int(log(S)+1)),S
will return an 8 digit number at 0,0 on the GS no matter what (if S's digits are less than
nice trick, i'll probably use it sometime >D
i may sound so noobish for asking this, but wat exactly is a memory leak? just when u use lables/ gotos and amount of free mem goes down?

I seen this on maxcoderz before and is nice, a memory leak I believe is when you use a loop of some kind like while or repeat, then within the loop use an exit which isn't from the main loop.
c1

CODE
ec1
Lbl 1
While K!=105
getkey->K
if Ans=21:Goto 1
endc2
ec2
This would give a bad memory leak (take up ram space I believe) if 2nd is pressed within the loop.

A memory leak is when the calc encounters a command that requires an End statement, but never reaches it. The reason is it keeps track of how many Ends there should be, and that eats up memory...

got a question:
Is there a difference between int( and iPart( ?
cause it seems to me that they give the same reults...

With the bases, here's one for the maximum number of digits in any base from any base (b is old base, n is old number, c is new base):
c1-->
CODE
ec1
iPart(dim(n)*ln(b)/ln(c)+1)
c2
ec2

iPart( goes towards 0, int( goes to the next lowest integer.

so if I do iPart(dim(42)*ln(13)/ln(10)+1) what will that do again?

That will return the maximum amount of digits in base 10 that a 42 digit number in base 13 can take up (which is 47). But n should be either a string (change to length( in that case) or a list for dim( to work properly).

Thanks for the "please install xLIB first thing" I just used it in my MS clone.
