[Mingw-users] code for an equivalent of sprintf ("%a", ***)

[Vincent T. <vt...@un...>]

Hey,

As mentioned in the wiki, printf-like functions can not handle the %a 
modifier character.

I need it in a library to convert from double to string and conversely 
using the format specified by %a.

I've already written a function that does the conversion of a string to a 
double. It's not very complicated.

Now, I would need to convert a double to a string, using the format 
that would be created by snprintf ("%a"). I'm a bit lost, as, as mentioned 
in the documentation of printf :

"If the precision is missing, it is taken as enough to represent the 
floating-point number exactly, and no rounding occurs." [1]

I don't know how to achieve that.

Does someone has ideas, or hints, or links to do such thing ?

thank you
