Actually, what I need is the D equivalent of the default
ToString() function we have in Dart and C#.
I don't think it means what you think it means:
void main() {
double value = -12.000123456;
int precision = 50;
import std.stdio;
writefln("%.*g", precision, value);
import std.format;
string str = format("%.*g", precision, value);
writeln(str);
}
Prints:
-12.000123456000000743415512260980904102325439453125
-12.000123456000000743415512260980904102325439453125
That's not quite the -12.000123456 that you'd get from C#'s
ToString().
Unfortunately, but that's still better though, thanks :)
All of them? Most implementations of conversion algorithms
actually stop when it's "good enough". AFAIR, D doesn't even
have it's own implementation and forwards to C, unless that
changed in recent years.
What I meant was that getting too many significant digits would
still be a better solution than not having them.
But indeed what I really need is a D function which gives a
better decimal approximation to the provided double constant,
exactly in the same way those in Dart and C# do.
Is there really no such function in D ?
