 1.#QO value in global variablewe are trying to program a holonomic drive and we are doing some sqrt(x^2 + y^2) .... stuff and get reasonable values in the first and 4th quadrants and MOST of the 3rd quadrant, but at maxX and maxY of the joystick, the global variable, which is a "float" becomes 1.#Q0 or 1.#Q0 as a value, and the motors stop. Any ideas??

Re: 1.#QO value in global variable a couple things,
1. It was pointed out to me that the ^ operator is not an exponent, but a shift... 2. You might be exceeding the limits of a type somewhere, so you might want to consider casting the value first
just a couple ideas. |

Re: 1.#QO value in global variable The ^ operator is bitwise xor, not shift. Shift is << for left shift and >> for right shift.
