BigInt.asUintN()
The BigInt.asUintN static method clamps a BigInt value to an unsigned integer value, and returns that value.
Try it
Syntax
BigInt.asUintN(bits, bigint);
Parameters
bits-
The amount of bits available for the integer size.
bigint-
The BigInt value to clamp to fit into the supplied bits.
Returns
The value of bigint modulo
2^bits, as an unsigned integer.
Examples
Staying in 64-bit ranges
The BigInt.asUintN() method can be useful to stay in the range of 64-bit
arithmetic.
const max = 2n ** 64n - 1n;
BigInt.asUintN(64, max);
// ↪ 18446744073709551615n
BigInt.asUintN(64, max + 1n);
// ↪ 0n
// zero because of overflow
