The int16 is to keep the bytes in the data type and not slip into 32bit
const scale = 8;
const d2f = (x) => Uint16Array.of(x * (1 << scale));
const f2d = (x) => Int16Array.of(x)[0] / (1 << scale);
const mul = (x, y) => Uint16Array.of(((x[0] >> 4) * (y[0] >> 2)) >> 2);
const a = d2f(-5); // ?
f2d(a) // ?
const b = d2f(0.8) // ?
f2d(b) // ?
const c = mul(a, b) // ?
// should be -4
f2d(c) // ?
