@extra-integer/parity v2.0.0

Gets n-bit parity of 32-bit integer.

For 1-bit parity bitParity is faster. This is part of package extra-integer.

integer.parity(x, n);
// x: an integer
// n: number of bits (1)

const integer = require('extra-integer');

integer.parity(7, 1);
// 1 (1,1,1 => 1)

integer.parity(8, 2);
// 2 (10,00 => 10)

integer.parity(63, 4);
// 12 (11,1111 => 1100)
