NAME
qecvt, qfcvt, qgcvt - convert a floating-point number to a string SYNOPSIS
#include
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 featuretestmacros(7)): qecvt(), qfcvt(), qgcvt(): SVIDSOURCE DESCRIPTION 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). ATTRIBUTES For an explanation of the terms used in this section, see attributes(7). ┌──────────┬───────────────┬──────────────────────┐ │Interface │ Attribute │ Value │ ├──────────┼───────────────┼──────────────────────┤ │qecvt() │ Thread safety │ MT-Unsafe race:qecvt │ ├──────────┼───────────────┼──────────────────────┤

Not supported by libc4 and libc5. Supported by glibc. NOTES These functions are obsolete. Instead, sprintf(3) is recommended. SEE ALSO ecvt(3), ecvtr(3), gcvt(3), sprintf(3) COLOPHON
