The BigInt.asUintN
static method is used to wrap a BigInt value to an unsigned integer between 0 and 2width-1.
BigInt.asUintN(width, bigint);
width
bigint
The value of bigint
modulo 2width
as an unsigned integer.
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
