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 || _BSD_SOURCE || _XOPEN_SOURCE >= 500

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).

CONFORMING TO

SVr4. Not seen in most common Unix implementations, but occurs in SunOS. Not supported by libc4 and libc5. Supported by glibc.

NOTES

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