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

NAME         top

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

SYNOPSIS         top

       #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         top

       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         top

       SVr4.  Not seen in most common UNIX implementations, but occurs in SunOS.  Not
       supported by libc4 and libc5.  Supported by glibc.

NOTES         top

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