Handling large numbers in JavaScript

[srivats123]

Hi All,

I am stuck with handling large numbers in JavaScript. If I try to OR 3305111602 and 65535, I get a negative number. I do not know the reason. What is the highest positive number that Javascript can handle. Can any one help me with this. Thanks.

Certainly larger than that. Somewhere on the order of 1.79e308

What do you mean you try to "OR" them?

alert(Number.MAX_VALUE);

Can you show some codes?

Why does javascript have a maximum value?
Has it got something to do with the number of digits it can remember at once?

It's got to do with the IETF floating point numbers standard.

And what is IETF floating point numbers standard?

Sorry, I had my acronyms messed up. IETF -> IEEE. IEEE 754 is the floating point number standard. It's a standard for how to encode numbers, used by almost all environments, It is the one used for floating point numbers in C99 (The international C standard), for instance. It has a few problems with rounding and such, but is otherwise a pretty good overall format, aiming at being both lightweight and cover as much as possible.
