Field NAN_DBL

Double precision constant for Not a Number.

NAN_DBL is considered unordered, which means all comparisons involving it are false except for not equal (operator !=). As a consequence, NAN_DBL == NAN_DBL is false but NAN_DBL != NAN_DBL is true.

Additionally, there are multiple bit representations for Not a Number, so if you must test if your value is NAN_DBL, use isnan().
