size_t \fBfmt_double\fP(char *\fIdest\fR,double \fId\fR,size_t

|
|

|
.SH DESCRIPTION
|
|
|
|
|
fmt_double writes an ASCII representation ('0' to '9', base 10) of
|
|
|
|
|
\fId\fR to \fIdest\fR and returns the number of bytes written. No more
|
|
|
|
|
than \fImaxlen\fR bytes will be written. \fIprec\fR digits will be
|
|
|
|
|
written, using scientific notation if necessary.
|
|
|
|
|
|
|
|
|
|
fmt_double does not append \\0.
|
|
|
|
|
|
|
|
|
|
If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_double returns the
|
|
|
|
|
number of bytes it would have written.
