NAME
qecvt, qfcvt, qgcvt - convert a floating-point number to a string
SYNOPSIS
#include <stdlib.h> char *qecvt(long double number, int ndigits",int*restrict"decpt, int *restrict sign); char *qfcvt(long double number, int ndigits",int*restrict"decpt, int *restrict sign); 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).
ATTRIBUTES
