• Most significant byte first: 0 , format.NORMAL , format.NETWORK , or
format.BIGENDIAN
• Least significant byte first: 1 , format.SWAPPED or format.LITTLEENDIAN
Details
This attribute selects the byte order in which data is written when you are printing data values with the
printnumber()
and
printbuffer()
functions. The byte order attribute is only used with the
format.SREAL , format.REAL , format.REAL32 , and format.REAL64 data formats.
format.NORMAL , format.BIGENDIAN , and format.NETWORK select the same byte order.
format.SWAPPED and format.LITTLEENDIAN select the same byte order. Selecting which to use
is a matter of preference.
Select the
format.SWAPPED or format.LITTLEENDIAN byte order when sending data to a
computer with a Microsoft Windows operating system.
Example
x = 1.23
format.data = format.REAL32
format.byteorder = format.LITTLEENDIAN
printnumber(x)
format.byteorder = format.BIGENDIAN
printnumber(x)
Output depends on the terminal program
you use, but will look something like:
