toString abstract method

String toString()
override

The shortest string that correctly represents this number.

All doubles in the range 10^-6 (inclusive) to 10^21 (exclusive) are converted to their decimal representation with at least one digit after the decimal point. For all other doubles, except for special values like NaN or Infinity, this method returns an exponential representation (see toStringAsExponential).

Returns "NaN" for double.nan, "Infinity" for double.infinity, and "-Infinity" for double.negativeInfinity.

An int is converted to a decimal representation with no decimal point.

Examples:

(0.000001).toString();  // "0.000001"
(0.0000001).toString(); // "1e-7"
(111111111111111111111.0).toString();  // "111111111111111110000.0"
(100000000000000000000.0).toString();  // "100000000000000000000.0"
(1000000000000000000000.0).toString(); // "1e+21"
(1111111111111111111111.0).toString(); // "1.1111111111111111e+21"
1.toString(); // "1"
111111111111111111111.toString();  // "111111111111111110000"
100000000000000000000.toString();  // "100000000000000000000"
1000000000000000000000.toString(); // "1000000000000000000000"
1111111111111111111111.toString(); // "1111111111111111111111"
1.234e5.toString();   // 123400
1234.5e6.toString();  // 1234500000
12.345e67.toString(); // 1.2345e+68

Note: the conversion may round the output if the returned string is accurate enough to uniquely identify the input-number. For example the most precise representation of the double 9e59 equals "899999999999999918767229449717619953810131273674690656206848", but this method returns the shorter (but still uniquely identifying) "9e59".
