NAME
qecvt, qfcvt, qgcvt - convert a floating-point number to a string
SYNOPSIS
#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
DESCRIPTION
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).
