Comparison between floating point numbers is best done using FP_Compare() - see CVI help for details.
Often you need to choose the maximum (or the minimum) of the two floating point numbers, and the most common approach is:
if (a > b) {
choose a
} else {
choose b
}
If you use FP_Compare instead of ">" you'll notice that FP_Compare is much slower than ">" (because it involves calculation of the ratio between the two numbers). This is extremely evident if you have to choose the maximum of several couples of numbers.
I think that the maximum (or the minimum) between two floating point numbers could be found in a more effective way, comparing the exponents of IEEE representation (for example), and calculate the ratio only if the exponents are equal.
For this reason I suggest two new functions FP_Max() and FP_Min() that would much more performant than the easy approach.
