This just illustrates the fact that computers generally don't store floating point numbers exactly. The result of the first division is only approximately 3.14159...etc. (Here it is, correct to 40 significant figures: 3.141597013388439272057065364416526894688, but even this is an approximation). Hence when this value is multiplied by the original divisor, it doesn't reproduce 360 * exactly, *though it's pretty close!

@ TitaniumRome

The commutative property is when a*b = b*a for multiplication; or a + b = b + a for addition.

Seems to me like the real question is:

what property does this expression/equation belong to best?

i think this is communitive property
