qfcvt: convert a floating-point number to a string

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).

ATTRIBUTES

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

Interface	Attribute	Value

qfcvt()	Thread safety	MT-Unsafe race:qfcvt
qgcvt()	Thread safety	MT-Safe

CONFORMING TO

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

NOTES
