  • In Java, what does NaN mean? - Stack Overflow
    16 NaN means "Not a Number" and is the result of undefined operations on floating point numbers like for example dividing zero by zero (Note that while dividing a non-zero number by zero is also usually undefined in mathematics, it does not result in NaN but in positive or negative infinity)
