source code for %e, %f and %g?

[Jonathan Wilson]

I can find source code in output.c for all the format specifications except
for the workings of %e, %f and %g (and also %E and %G).
Where is the source code for these functions?
If it is not included, does anyone know why not?

In VC7.1, I can see them on line 744 onwards. What version are you
looking at?

AFAIK, MS has never provided source code for FP conversion routines or most
other FP stuff. I'm not sure why that is. Could be licensing issues, could
be that it's considered too valuable, etc.

Ahh, I can't find any code for the entries in the _cfltcvt_tab table,
which is what you are wanting I suppose.

In any Linux distribution?

This is indeed due to licensing issues.

I assume then that licencing issues are why other pieces of code (e.g.
exception handling code) are also missing...

Yep.
