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

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.  Supported by glibc.

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