QECVT(3)                   Linux Programmer's Manual                  QECVT(3)



NAME
       qecvt, qfcvt, qgcvt - convert a floating-point number to a string

SYNOPSIS
       #include <&lt;stdlib.h>&gt;

       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.
