: Because it is trivial to roll your own:
: #define	Round( d )	floor( (d) + 0.5 )	/* requires <math.h> */
: and because there was no established existing practice (e.g. the library
: Base Document did not specify such a function).

I'm afraid it's not that trivial.  That doesn't provide the preferred
round-to-even-when-there-is-a-tie.  It is a _pain_ that the function
nint() isn't portable.  The Base Document didn't specify fsetpos() either,
but that didn't stop ANSI filling in a nasty gap.

What's the NCEWG up to?  Are they likely to address this?
