QECVT(3)                                            Linux Programmer's Manual                                           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 || _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.

SEE ALSO
       ecvt(3), ecvt_r(3), gcvt(3), sprintf(3)
