qfcvt (3)

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).
