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.
