Short for Not a Number, a floating-point special value produced by operations with no numeric result, such as 0 ÷ 0 or the square root of a negative number. It has an all-ones exponent and a nonzero significand, and compares unequal even to itself.
Field: Computer Arithmetic
Under IEEE 754, NaN is "not a number," so it compares unequal to everything, including itself: x == x is false (and x != x is true).
When x is NaN, what does evaluating x == x give in most pro…Stored values 0 and all ones (255) are reserved for subnormals and for infinity and NaN.
