Javascript parseInt on large negative number gives NaN -

when this:

var x = parseint("–2147483648"); console.log(x);

i value as:

nan

why happen?

i want test if number in range of c (int), doing above, not work. also, want c (long), there way this?

for example: if do:

var x = parseint("-9223372036854775808"); console.log(x);

now, know (-+)2^53 limit of numbers in javascript. there other way test if given value in form in range of long or int?

it should work fine, problem you're using wrong character, ndash – vs hyphen -:

var x = parseint("-2147483648"); console.log(x);

if copy/paste you'll see works now.
