i defined var x = 0704 ; and the o/p was 452 .can some one explain why

Question

is there some limit to var

Answer 1

Because that's how you define an octal in JS, it starts with 0.

Answer 2

This is octal system, 0704 = 8×8×7 + 4 = 452.

Answer 3

I don't know really, HEX (base 16) can be used for memory addresses but octal I'm not sure I never used it.

Answer 4

Octal number system is based on the number 8. Starting from the right you have 4×8^0 which is 4, then the second number is 0, which is 0×8^1 = 0. Third number is 7, so it is 7×8^2. You add them all up and you get 452...

Answer 5

No, any number that starts with 0. Like 0704, or 071111 or whatever.
