I just wanted t know what the largest number darkbasic can hold is I am writing a program that uses some pretty big numbers e.g. 75 to the power of 7. I no in other languages you can make a number floating point or sumthing like that but how do i get darkbasic to be capable of holding reely big numbers?

If u cant beat the best give up and go home

I think infinnitiy is the limmit, I haven't read about a largest number anywhere. (I think it would have been noted in the help file at the explenation of a variable, just a the maximum of objects)

please reply

There is a limit, but I'm not sure what it is.

The maximum of a 16-bit integer is somewhere around 65K, and a 32-bit integer is about 4.3B, not sure about the reals though.

the nutty proffesor,

What type of integer? Integer is a type. The three types of variables in DarkBasic are string$, real# and integer, and can all be used by placing their associative symbols in front of the name of the variable.

What do you mean by inaccurately?

I think he means using reals, as a large number would be stored like in scientific notation.

A large number would be stored as 1.X to the power of Y.

It can store large values, but loses some accuracy.
