parseInt and Number casting result in different number from string

Question

I'm trying to get a number from a string but it's returning the wrong value

Number("580682945690490185")
580682945690490200

parseInt("580682945690490185")
580682945690490200

console.log(580682945690490185) nothing to do with the methods. — epascarello

That number is bigger than the maximum safe number as in IEEE 754 you can only safely represent numbers between -(2^53 - 1) and 2^53 - 1.

You should try with BigInt which has no limit
