Description
Streaming out double values with Xmlize leads to a call to FormatDouble(x), which in turn uses
String FormatDouble(double a) { return IsNull(a) ? String() : IsNaN(a) ? "?" : FormatDouble(a, 10, FD_REL); }
Loosing so 5 of the 15 precision digits of double values.
In some precision sensitive apps this is just not enough; I'd suggest, either to change the default digits
of FormatDouble(x) to 15 or to use the extended version with 15 digits when streaming out xml data.
Another nice option would be to provide some global setting value to allow change of default number of digita.
