Returns an exponential string-representation of this
.
Converts this
to a double before computing the string representation.
If fractionDigits
is given then it must be an integer satisfying: 0 <= fractionDigits <= 20
. In this case the string contains exactly fractionDigits
after the decimal point. Otherwise, without the parameter, the returned string uses the shortest number of digits that accurately represent this.
If fractionDigits
equals 0 then the decimal point is omitted. Examples:
1.toStringAsExponential(); // 1e+0 1.toStringAsExponential(3); // 1.000e+0 123456.toStringAsExponential(); // 1.23456e+5 123456.toStringAsExponential(3); // 1.235e+5 123.toStringAsExponential(0); // 1e+2
String toStringAsExponential([int fractionDigits]);
