Unsigned multiplication of Q64.64 values.
Mathematically this should produce a Q128.128 value; we keep the central 128 bits, representing the Q64.64 result. We assert on integer overflow beyond the 64-bit integer portion.
[in] | a | First factor. |
[in] | b | Second factor. |
It might be tempting to just use a *
b and be done with it, but it's not that simple. With a and b as 128-bit integers, a *
b mathematically produces a 256-bit result, which the computer truncates to the lowest 128 bits. In our case, where a and b are interpreted as Q64.64 fixed point numbers, the multiplication mathematically produces a Q128.128 fixed point number. We want the middle 128 bits from the result, truncating both the high and low 64 bits. To achieve this, we carry out the multiplication explicitly with 64-bit operands and 128-bit intermediate results.
