For a given CPU integer operations a+b, and å b take almost Ical amount floating point (32 bit) multiplication takes approximately 3x as long. Floating point additions and integer additions take nearly identical times. (Yes, those are nearly real numbers for Intel Haswell CPU's). For a program that is 20% logic operations (which take the same no matter what), 40% additions and 40% multiplications, derive a formula to calculate the estimated performance of changing the maths from Integer to Floating point operations on the same CPU
