Usage
format = format.data
format.data = format
value
The format to use for data, set to one of the following values:
•
ASCII format:
1
or
format.ASCII
•
Single-precision IEEE Std 754 binary format:
2
,
format.SREAL
, or
format.REAL32
•
Double-precision IEEE-754 binary format:
3
,
format.REAL
,
format.REAL64
, or
format.DREAL
Details
The precision of numeric values can be controlled with the
format.asciiprecision
attribute. The byte order
of
format.SREAL
,
format.REAL
,
format.REAL32
, and
format.REAL64
can be selected with the
format.byteorder
attribute.
The IEEE Std 754 binary formats use four bytes each for single-precision values and eight bytes each for
double-precision values.
When data is written with any of the binary formats, the response message starts with “#0” and ends with a new
line. When data is written with the ASCII format, elements are separated with a comma and space.
NOTE
Binary formats are not intended to be human readable.
Example
format.asciiprecision = 10
x = 3.14159265
format.data = format.ASCII
printnumber(x)
format.data = format.REAL64
printnumber(x)
3.14100
