DESCRIPTION

14       fmt_double writes an ASCII representation ('0' to '9', base 10) of d to
15       dest and returns the number of bytes  written.   No  more  than  maxlen
16       bytes  will  be written.  prec digits will be written, using scientific
17       notation if necessary.
18
19       fmt_double does not append \0.
20
21       If dest equals FMT_LEN (i.e. is zero), fmt_double returns the number of
22       bytes it would have written.
