qecvt(3)                   Library Functions Manual                   qecvt(3)

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

LIBRARY
       Standard C library (libc, -lc)

SYNOPSIS
       #include <stdlib.h>

       [[deprecated]] char *qecvt(long double number, int ndigits,
                                  int *restrict decpt, int *restrict sign);
       [[deprecated]] char *qfcvt(long double number, int ndigits,
                                  int *restrict decpt, int *restrict sign);
       [[deprecated]] char *qgcvt(long double number, int ndigit, char *buf);

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

       qecvt(), qfcvt(), qgcvt():
           Since glibc 2.19:
               _DEFAULT_SOURCE
           In glibc up to and including 2.19:
               _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).
