    NAME

    ecvt_r, fcvt_r, qecvt_r, qfcvt_r - convert a floating-point number to a string
     
    

    SYNOPSIS

    #include <stdlib.h>
    
    int ecvt_r(double number, int ndigits, int *decpt,
               int *sign, char *buf, size_t len);
    
    int fcvt_r(double number, int ndigits, int *decpt,
               int *sign, char *buf, size_t len);
    
    int qecvt_r(long double number, int ndigits, int *decpt,
               int *sign, char *buf, size_t len);
    
    int qfcvt_r(long double number, int ndigits, int *decpt,
               int *sign, char *buf, size_t len);
    

    Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

    ecvt_r(), fcvt_r(), qecvt_r(), qfcvt_r(): _SVID_SOURCE || _BSD_SOURCE || _XOPEN_SOURCE >= 500  

    DESCRIPTION

    The functions ecvt_r(), fcvt_r(), qecvt_r() and qfcvt_r() are identical to ecvt(3), fcvt(3), qecvt(3) and qfcvt(3), 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).  

    RETURN VALUE

    These functions return 0 on success, and -1 otherwise.  

    CONFORMING TO

    These functions are GNU extensions.  

    NOTES

    These functions are obsolete. Instead, sprintf(3) is recommended.
