char *qecvt(long double number, int ndigits, int *decpt, int *sign);
char *qfcvt(long double number, int ndigits, int *decpt, int *sign);
char *qgcvt(long double number, int ndigit, char *buf);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
DESCRIPTIONThe functions qecvt(), qfcvt(), and qgcvt() are identical to ecvt(3), fcvt(3), and gcvt(3) respectively, except that they use a long double argument number. See ecvt(3) and gcvt(3).
ATTRIBUTESFor an explanation of the terms used in this section, see attributes(7).

CONFORMING TOSVr4. Not seen in most common UNIX implementations, but occurs in SunOS. Supported by glibc.
