NAME
       ecvt_r, fcvt_r, qecvt_r, qfcvt_r - convert a floating-point number to a
       string

SYNOPSIS
       #include 

       int ecvt_r(double number, int ndigits, int *decpt,
		  int *sign, char *buf, size_t len);

       int fcvt_r(double number, int ndigits, int *decpt,
		  int *sign, char *buf, size_t len);

       int qecvt_r(long double number, int ndigits, int *decpt,
		  int *sign, char *buf, size_t len);

       int qfcvt_r(long double number, int ndigits, int *decpt,
		  int *sign, char *buf, size_t len);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       ecvt_r(), fcvt_r(), qecvt_r(), qfcvt_r(): _SVID_SOURCE || _BSD_SOURCE
       || _XOPEN_SOURCE >= 500

DESCRIPTION
       The functions ecvt_r(), fcvt_r(), qecvt_r() and qfcvt_r() are identical
       to ecvt(3), fcvt(3), qecvt(3) and qfcvt(3), respectively,  except  that
       they do not return their result in a static buffer, but instead use the
       supplied buf of size len.  See ecvt(3) and qecvt(3).

RETURN VALUE
       These functions return 0 on success, and -1 otherwise.

CONFORMING TO
       These functions are GNU extensions.

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