DESCRIPTION <\/a> <\/h2>\n

The gcvt<\/b>() function converts number<\/i> to a minimal length null-terminated ASCII string and stores the result in buf<\/i>. It produces ndigit<\/i> significant digits in either printf<\/b>(3) F format or E format.<\/p>\n

RETURN VALUE <\/a> <\/h2>\n

The gcvt<\/b>() function returns buf<\/i>.<\/p>\n

CONFORMING TO <\/a> <\/h2>\n

Marked as LEGACY in POSIX.1-2001. POSIX.1-2008 removes the specification of gcvt<\/b>(), recommending the use of sprintf<\/b>(3) instead (though snprintf<\/b>(3) may be preferable).<\/p>\n
