really really really big numbers in VB?

lets say i need to work iwth integers in the nonillion range (1,000,000,000,000,000,000,000,000,000,000) in a for loop.. has anyone developed a class to handle this sort of thing? i know it doesn't sound realistic to have a for loop that long but i need to use it!

is there anything i can do?

can a moderator move this to the general programming foruM?

Declare it as Double. Integers will only give you around 32,000. Using Double will give you a number somewhat like the one you specified.

Code:

---

Dim MyValue as Double

i have a book (vb6 win32 api tutorial by jason bock, wrox presS)
he uses UDT's to express big numbers, he dunnit like this

Code:

---

type thisthing
lower32 as long
higher32 as long

---

that makes it like 64 bits or something.... I am not very sure, the author didnt really say how to use it, he just said something about it.

oops.....

Code:

---

end type

---

Yes, but you could just type one word and make it 64 bits.
Currency is 64 bits and I think Double is 96 bits.

no, a currency is only 64 bits, Dennis, when Jason Bock uses his LARGE_INTEGER use a currency instead, it makes the maths so much easier.

also, watch for memory leaks in his code, he forgets some deleteobjects etc.

Other than that it's a great book, those of you thinking of buying it, don't be discouraged by the scary picture on the front.

Yes, that's what I said, didn't I?

I meant a double is 64 bits, I just forgot what I meant while typing.
