Standard C library (libc, -lc)

#include <stdlib.h>

[[deprecated]] char *qecvt(long double number, int ndigits,
                           int *restrict decpt, int *restrict sign);
[[deprecated]] char *qfcvt(long double number, int ndigits,

[[deprecated]] char *qgcvt(long double number, int ndigit, char *buf);

qecvt(), qfcvt(), qgcvt():

    Since glibc 2.19:
        _DEFAULT_SOURCE
    In glibc up to and including 2.19:
        _SVID_SOURCE

The 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).

For an explanation of the terms used in this section, see attributes(7).

SVr4. Not seen in most common UNIX implementations, but occurs in SunOS. Supported by glibc.

These functions are obsolete. Instead, snprintf(3) is recommended.

ecvt(3), ecvt_r(3), gcvt(3), sprintf(3)

ecvt(3), ecvt_r(3).

The man pages qfcvt(3) and qgcvt(3) are aliases of qecvt(3).
