Error in Javascript parseint value with very large number

Question

When converting a number into decimal string format to the numeric value, I get the wrong number:

parseInt("36428971654192132")
// 36428971654192130

Answer 1

According to Javascript.info, the guy number cannot correctly represent integers larger than 2^53-1, or 9,007,199,254,740,991.

Comparing:

• 9007199254740991
• 36428971654192132

Try to use Bigint:

BigInt("36428971654192132");
