interleave

Interleave bits of two int16s.

Similar: merge, interleave.

interleave(x, y)
// x: first int16
// y: second int16
// → int32

const xbit = require('extra-bit');

xbit.interleave(0x0000, 0xFFFF);
// → 1431655765 (0x55555555)

xbit.interleave(0x1234, 0x1234);
// → 51121968 (0x030C0F30)

xbit.interleave(0x1234, 0x4321);
// → 302845473 (0x120D0E21)
