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);
