Multiplication of floating-point numbers is not associative. Take for instance:
<smallest possible positive number> * 0.5 * 2
When evaluated like that:
(<SPPN> * 0.5) * 2
the result is 0 * 2 = 0
And when evaluated the other way around:
<SPPN> * (0.5 * 2)
the result is <SPPN> * 1 = <SPPN>
double sppn = Double.MIN_VALUE;
double first = sppn * (0.5 * 2);
double second = (sppn * 0.5) * 2;
System.out.println(sppn);
System.out.println(first);
System.out.println(second);
