The data format for data printed using the printnumber and printbuffer functions.
To read data format:
fmt = format.data
To write data format:
format.data = fmt
fmt: Set to one of the following values:
1 or format.ASCII ASCII format.
2 or format.SREAL Single precision IEEE-754 binary format.
2 or format.REAL32 Single precision IEEE-754 binary format.
3 or format.REAL Double precision IEEE-754 binary format.
3 or format.REAL64 Double precision IEEE-754 binary format.

This attribute selects the data format used to print data values with the printnumber
and printbuffer functions.

The precision of the ASCII format can be controlled with the
(on page 9-127) attribute. The byte order of SREAL, REAL, REAL32, and REAL64
can be selected with the

REAL32 and SREAL select the same single precision format. REAL and REAL64
select the same double precision format. They are alternative identifiers. Selecting
which to use is a matter of preference.

The IEEE-754 binary formats use 4 bytes each for single precision values and 8
bytes each for double precision values.

When data is written with any of the binary formats, the response message will start
with "#0" and end with a new line. When data is written with the ASCII format,
elements will be separated with a comma and space.
