toString
For Common, JVM, JS
Returns a string representation of the object.
For Native
Returns the string representation of this Double value.
Note that the representation format is unstable and may change in a future release.
However, it is guaranteed that the returned string is valid for converting back to Double
using String.toDouble, and will result in the same numeric value.
The exact bit pattern of a NaN
double is not guaranteed to be preserved though.
