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).

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.  Supported by
       glibc.

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