 		 #142787 - Integer < 65536?
Responding to: ???'s previous message
Dan Henry said:
Unless AxilAngle is a float, all subexpressions on the right hand side of the assignment operator will be performed using integer arithmetic and conversion to a float will be performed when assigned to 'tmp'.


...but with the expression:

tmp = 65536 - (10 * AxisAngle + 460) * 221184 / 120000;

it worked fine, even with (10 * 180 + 460) * 221184 > 65536. Why is this happen? Or it just happened to work?
