ecvt_r(3) -- Linux man page
NAME
ecvt_r, fcvt_r, qecvt_r, qfcvt_r - convert a floating-point number to a string
SYNOPSIS
#include <stdlib.h>
char *ecvt_r(double number, int ndigits, int *decpt,
int *sign, char *buf, size_t len);
char *fcvt_r(double number, int ndigits, int *decpt,
int *sign, char *buf, size_t len);
char *qecvt_r(long double number, int ndigits, int *decpt,
int *sign, char *buf, size_t len);
char *qfcvt_r(long double number, int ndigits, int *decpt,
int *sign, char *buf, size_t len);
DESCRIPTION
The functions
ecvt_r,
fcvt_r,
qecvt_r
and
qfcvt_r
are identical to
ecvt,
fcvt,
qecvt
and
qfcvt,
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).
NOTES
These functions are obsolete. Instead,
sprintf()
is recommended.
CONFORMING TO
These functions are GNU extensions.
