DESCRIPTION
The gcvt() function converts
number to a minimal
length null-terminated ASCII string and stores the result in
buf. It produces
ndigit significant
digits in either printf(3) F format or E
format.
CONFORMING TO
Marked as LEGACY in POSIX.1-2001. POSIX.1-2008 removes the
specification of gcvt(),
recommending the use of sprintf(3) instead (though
snprintf(3) may be
preferable).
