 		 #142781 - Range of Variables
Responding to: ???'s previous message
Thank you for your suggestion.

As you have pointed out, when "AxisAngle = 180", (10 * 180 + 460) * 22118400 does exceed 2^32.
Now I don't understand what the textbook says about the range of the float variable because the calculated value can still fit in the range of a float variable (1.xxxE-38 to 1.xxxE+38), like "tmp" in the code.

So the complier does not look after that, does it? It is new to me, and I have no idea what level of "intelligence" it has.
