qecvt, qfcvt, qgcvt − convert a floating-point number to a string
#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);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
qecvt(), qfcvt(), qgcvt(): _SVID_SOURCE
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).
SVr4. Not seen in most common Unix implementations, but occurs in SunOS. Not supported by libc4 and libc5. Supported by glibc.
These functions are obsolete. Instead, sprintf(3) is recommended.
ecvt(3), ecvt_r(3), gcvt(3), sprintf(3)
