Hay guys, i have 2 floats, which both comes from input boxes.
I need to compare these 2 floats, if one is negative and one is positive thrown an error. If they're both positive, or both negative, thats fine.
Multiply them together.
If the answer is positive then they are both the same sign.
If the answer is negative then they are of opposite sign.
If the answer is zero (within some value to take care of rounding error) then one or both are zero and you'll have to check them individually. You'll then have to decide whether 0 to be treated as positive or negative in your scenario.
