qecvt, qfcvt, qgcvt - convert a floating-point number to a string
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)):
DESCRIPTIONThe 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).
ATTRIBUTESFor an explanation of the terms used in this section, see attributes(7).
|qecvt()||Thread safety||MT-Unsafe race:qecvt|
|qfcvt()||Thread safety||MT-Unsafe race:qfcvt|
CONFORMING TOSVr4. Not seen in most common UNIX implementations, but occurs in SunOS. Supported by glibc.
NOTESThese functions are obsolete. Instead, snprintf(3) is recommended.
