qecvt, qfcvt, qgcvt - convert a floating-point number to a string
Návod, kniha: Linux Programmer's Manual
#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);
The functions
qecvt,
qfcvt and
qgcvt are identical to
ecvt,
fcvt and
gcvt respectively, except that they use a
long double argument
number. See
ecvt(3) and
gcvt(3).
These functions are obsolete. Instead,
sprintf() is recommended.
SysVr4.0. Not seen in most common Unix implementations, but occurs in SunOS. Not
supported by libc4 and libc5. Supported by glibc.
ecvt(3),
ecvt_r(3),
gcvt(3),
