NAME

       fmt_double - write an ASCII representation of a double

SYNTAX

       #include <fmt.h>

       size_t fmt_double(char *dest,double d,size_t maxlen,size_t prec);

DESCRIPTION

       fmt_double  writes  an  ASCII representation ('0' to '9', base 10) of d to dest and returns the number of
       bytes written.  No more than maxlen bytes will be written.  prec digits will be written, using scientific
       notation if necessary.

       fmt_double does not append \0.

       If dest equals FMT_LEN (i.e. is zero), fmt_double returns the number of bytes it would have written.
