you would probably get that answer faster if you ask one of the moderaters directly i would suggest asking CPhill he is one of the moderaters that stay on of the longest so you would have a better shot at getting your answer
Example:
-2.5 x 3+(3x4+ 2^3)^2 x3 = 1192.5
It seems to do so....there was some discussion some time back about -2^2 = -4 because it does the exponent first then does the negative so if you want -2 squared you have to use parens (-2)^2 = 4
