qfcvt_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.
