Re: Floating Points and rounding

you can most certainly deal with floating point numbers! just be careful about typecasting, because PIC C defaults to integers.... so you have to typecast everything.

multiplying by 180/127 is not a good idea... first of all because the range on the servo is not 180... its either 160 or 210 (i forgot). multiply by the decimal... you wil run into less problems.

otherwise...

float PAN_DEGREE = (160.0f / 127.0f);
TRUE_PAN_DEGREE = (float)PAN_SERVO * PAN_DEGREE;

notice the forced decimals and the f.
