In radians, multiply by 360, divide by 2pi == Atan () - don't work! Here is a bit of my code: float direction; direction = atan ( 120 / 90 ); printf ("%f", direction"); And output is this: 0.927295 But with calculator it is: tan^-1 (120 / 90) = 53.1301023... Is atan () right inverse tan function? Greetings, Jarkko DOT Kahkonen AT mbnet DOT REMOVETHAT DOT fi
