.TH fmt_double 3 |
|
.SH NAME |
|
fmt_double \- write an ASCII representation of a double |
|
.SH SYNTAX |
|
.B #include <fmt.h> |
|
|
|
size_t \fBfmt_double\fP(char *\fIdest\fR,double \fId\fR,size_t |
|
\fImaxlen\fR,size_t \fIprec\fR); |
|
.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. |
