QECVT(3) Linux Programmer's Manual QECVT(3)

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).

see_pthreads(7))">)">Multithreading (see pthreads(7))

The qecvt() and qfcvt() functions are not thread-safe.

The qgcvt() function is thread-safe.

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, snprintf(3) is recommended.

ecvt(3), ecvt_r(3), gcvt(3), sprintf(3)
