setAs

Set bits as per mask.

Alternatives: set, setAs.
Similar: get, set, toggle.

setAs(x, m, [f])
// x: an int32
// m: bit mask
// f: bit value (1)

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

xbit.setAs(8, 2, 1);
// → 10 (0x8 set 0x2 ⇒ 0xA)

xbit.setAs(15, 3, 0);
// → 12 (0xF clear 0x3 ⇒ 0xC)

xbit.setAs(0x1234, 0x430, 1);
// → 5684 (0x1234 set 0x430 ⇒ 0x1634)
