Floating Points and rounding

[teh_pwnerer795]

Hey guys,

for the camera this year, i'd like to set the PAN and TILT values into degrees. Now im sure there is code already formulated somewhere within kevin code. but i'd rather wrap my mind around how to properly do it.

This is my code so far.

//(1.42 degree) per (1pwm)
PAN_DEGREE = (180 / 127);
True_PAN_Degree = PAN_DEGREE * PAN_SERVO;

Now. my question to u guys. i want to use floating points instead of intergers. i would also like to noe how to round the floating point number to 4 decimals. However. i do know that floating points do take alot of space and processing power! but! the maximum value being produced is 180. ( 180 degrees). If you could leave some input that would be great
