# toString method

String toString ()
override

Provide a representation of this double value.

The representation is a number literal such that the closest double value to the representation's mathematical value is this double.

Returns "NaN" for the Not-a-Number value. Returns "Infinity" and "-Infinity" for positive and negative Infinity. Returns "-0.0" for negative zero.

For all doubles, `d`, converting to a string and parsing the string back gives the same value again: `d == double.parse(d.toString())` (except when `d` is NaN).

## Implementation

    String toString();
