QECVT(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).

ATTRIBUTES

  Multithreading (see pthreads(7))
The qecvt() and qfcvt() functions are not thread-safe.

The qgcvt() function is thread-safe.

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, snprintf(3) is recommended.
