"Not a Number", an invalid floating-point value. [constant NAN] has special properties, including that it is not equal to itself ([code]NAN == NAN[/code] returns [code]false[/code]). It is output by some invalid operations, such as dividing floating-point [code]0.0[/code] by [code]0.0[/code].
"Not a Number", an invalid floating-point value. [constant NAN] has special properties, including that [code]!=[/code] always returns [code]true[/code], while other comparison operators always return [code]false[/code]. This is true even when comparing with itself ([code]NAN == NAN[/code] returns [code]false[/code] and [code]NAN != NAN[/code] returns [code]true[/code]). It is returned by some invalid operations, such as dividing floating-point [code]0.0[/code] by [code]0.0[/code].
