javascript problem with parseint

Workarounds for JavaScript parseInt octal bug

I am trying to parse an integer number.

a = parseInt("0005")  <- gives 5
a = parseInt("0008")  <- gives 0

Can someone explain what's happening? It doesn't make any sense to me.

Thanks Pekka. This solved the problem. Can you add your comment as an answer so I can accept it and close off the questions. — Dave Heart, Jun 12 '11 at 17:30

When parseInt has a leading 0 and a radix parameter isn't specified, it assumes you want to convert the number to octal. Instead you should always specify a radix parameter like so:

a = parseInt("0008", 10) // => 8

Numbers starting with 0 are parsed as octal by parseInt, unless you specify a radix to use.

You can force parseInt to parse as decimal by doing

a = parseInt("0008", 10)
