[RESOLVED] Long number data type

[BubbleLife]

Hey all (again, sorry for all the questions ^^;; )

I'm just wondering if there's a data type or if one can be made for storing very long numbers, but being able to perform mathmatical calculations on them? (i.e. not a string).

I want to use the Rnd function to generate a 20-digit number, e.g. 40229603967719402863. I can't store it int/long/etc as it's too long, I can store it in Double but then it makes it a floating point number.

Soo.. Any way to generate a number of this size and have it display the full value? I'm trying to generate a unique ID, you see

I think Currency can hold the most number of digits. Not sure, though.

Ah, it can cope with 14. I guess that's enough, not much chance of two machines generating the same 14 digit number

but be aware that a currency holds a 2 digit float. what u can do is create a datatype u'reself. a wild thought it may be but here it goes.

public type myLong
    long1 as long
    long2 as long
    long3 as long
end type

so what i am thinking here is to generate numbers with digits divisible by 3 and store the digits in parts in the long1, long2 and long3. what do u think???

Well, you would have to parse it both ways.

222 is 2 * 10^2 + 2 * 10 ^ 1 + 2

but it would be hard to figure out, even if you padded it with zeroes.

000002 000002 000002

i understand the problem but if u need an integer that is beyond the reach of standard data types, u r left with no other choice than do it the hard way.
