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, sprintf(3) is recommended.
