I'm trying to add formatted output to my decimal arithmetic
module. Decimals should format like floating point, using 'E',
'F' and 'G', etc.
I would expect a format string like "%9.6e" to parse as width =
9, precision = 6, using exponential notation.
In std.format there is a FormatSpec struc

What gets output at the end is clearly an array containing a subset of the

Hi Dmitry,
Thanks for your thoughts and for pointing me at some aspects of D I'd not come
across before.
I think that if you like function pointer thing, you'd love D's delegates and
lambdas. If templates are too pervasive it might be better just use little bit
of dynamic stuff.

Yeah, I think those templates were added in the last release or two. The

Hello all,
My programming experience is mostly in C with some C++, so much of the
programming style of D is not familiar to me. With that in mind, I thought I'd

What I thought I'd do is implement some clever algorithms fo

On the contrary: it requires work to implement limitations. Therefore

Not having descovered any benefit of a limitation might point to
