QECVT(3) Linux Programmer's Manual QECVT(3)
qecvt, qfcvt, qgcvt - convert a floating-point number to a string
#include <stdlib.h>
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)):
qecvt(), qfcvt(), qgcvt(): _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.
