All of the API's boolean operator comparisons to Float.NaN or Double.NaN are invalid

[Tim Boylan]

All of the API's boolean operator comparisons to Float.NaN or Double.NaN are invalid.

The equality operator == returns false if either operand is NaN.

The inequality operator != returns true if either operand is NaN .

Even Float.NaN == Float.NaN will return false and

Float.NaN != Float.NaN will return true

You need to use from the Float class: static boolean Float.isNaN(float v)

Returns true if the specified number is a Not-a-Number (NaN) value, false otherwise.

or for double use the corresponding one for Double.
