\|		Here is a rough approximation of float multiplication (source): float rough_float_multiply(float a, float b) { constexpr uint32_t bias = 0x3f76d000; return bit_cast(bit_cast(a) + bit_cast(b) - bias); } We're casting the floats to ints, adding them, adjusting the exponent, and returning as float. If you think about it for a second you will realize that since...	34.6 parsecs away Travel
