cast long string to number using parseInt in javascript?

Question

I want to cast this id 59aa94878d08a20758deed83 to number, I first tried without argument, I only got 59.

var x=parseInt('59aa94878d08a20758deed83', 24);
console.log(x);

above won't return 59aa94878d08a20758deed83 in number?

Do you want to convert an *hexadecimal* number to a *decimal* number? — Gerardo Furtado, Sep 10 '17 at 13:48
Do you mean from hexadecimal to decimal? Try `parseInt('59aa94878d08a20758deed83', 16);` — Tholle, Sep 10 '17 at 13:48

@GerardoFurtado what do you mean by that? I just want the id in exact charactor but in number. — Jenny Mok, Sep 10 '17 at 13:51
`Number` types in javascript cannot contain any alpha characters, only numbers. Unless you are trying to *convert* a hexadecimal or other type of number, your question doesn't make much sense. — skyline3000, Sep 10 '17 at 14:05

Just use correct radix. If it is real hexadecimal number, use radix 16, not 24...

console.log(parseInt('59aa94878d08a20758deed83', 16))

I got this answer `2.7750384674146666e+28` is this correct? – Jenny Mok Sep 10 '17 at 13:50
I dont know. It must know author. It just seems like hexadecimal number, so I convert it from hexa to decimal. I have no idea whether it is correct or not. – Sep 10 '17 at 13:52
