SYNOPSIS

15       char *qgcvt(long double number, int ndigit, char *buf);

DESCRIPTION

23       The functions qecvt(), qfcvt() and qgcvt() are  identical  to  ecvt(3),
24       fcvt(3)  and  gcvt(3)  respectively, except that they use a long double
25       argument number.  See ecvt(3) and gcvt(3).
26

CONFORMING TO

28       SVr4.  Not seen in most common  Unix  implementations,  but  occurs  in
29       SunOS.  Not supported by libc4 and libc5.  Supported by glibc.
30

NOTES

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