UBB.Developers Forums Community Development Programming PHP and Server-side Scripting Order of Precedence Question

Actually, atom, that only works for even exponents. If you take a negative number to an odd power, it will still be negative. Ex: (-2) ** 3 = -8 ... (-2)(-2)(-2) = -8

Oh yes, and you should only use integers as exponents. Otherwise, if you take (-2) ** 3.5 you will get a non-real answer. It will do that for all decimals that are odd (after the decimal place, that is). If you dont know why it does that, is because 3.5 = 7/2. That means you are taking (-2 ** 7) which results in a negative number, and then taking the square root of it. Jeez, enough math lesson for now Hope that explains a bit.
