Integers in JavaScript
- by muntoo
I'm a beginner to Javascript so forgive me if I sound dumb because I learned some Javascript from W3Fools (which are really difficult tutorials - they don't explain anything I want to know, but everything I probably can guess from my experience with C++).
I may be switching over to MDN, but if you can recommend any other tutorials, that be great.
Anyways, so here's my question:
I just read a few lines of this, and apparently:
Numbers in JavaScript are
"double-precision 64-bit format IEEE
754 values", according to the spec.
This has some interesting
consequences. There's no such thing as
an integer in JavaScript, so you have
to be a little careful with your
arithmetic if you're used to math in C
or Java.
I've already seen that there are few of the data types (for variables) I'm used to from C++. But I didn't expect all numbers to automatically be floats. Isn't there any way to use integers, not float? Will a future version of JavaScript support ints?
