Parseint Behaving Different In Ie And Chrome

i have parseInt function. for 010 as input : output in IE : 8 output in chrome and firefox: 10 for 099 as input: output in IE : 0 output in chrome and firefox: 99 Could someone

Solution 1:

Actually I would argue IE is doing things correctly* here . parseInt for a string starting with a 0 is treated as octal input.

To fix the problem, specify the base (in this case, you want decimal - 10):

num = parseInt(str, 10);

* In this case "correctly" really means "traditionally". The specification has actually changed. Technically, a string starting with 0 can be treated as either octal OR decimal, depending on the implementor's whim, where decimal is now preferred:

If radix is undefined or 0 (or absent), JavaScript assumes the following:

• If the input string begins with "0", radix is eight (octal) or 10 (decimal). Exactly which radix is chosen is implementation-dependent. ECMAScript 5 specifies that 10 (decimal) is used, but not all browsers support this yet. For this reason always specify a radix when using parseInt.
