I wouldn't write it like that; IMO it's better to write:
writefln("%.*f", double.dig, a);
So that you don't give the wrong impression that there are more digits
than are actually there. Using double.dig also lets you see all the
digits that *are* there, not a rounded value, that the OP was
complaining about.
...
double.dig gets you the number of significant digits in total. The
number of significant digits after the decimal point is dependent on the
exponent.
