fmt_double(3)		   Library Functions Manual		 fmt_double(3)

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.
