format
The format attributes are used to configure the output formats used by the print, printnumber,
and printbuffer functions. These attributes are used to set the data format (ASCII or binary),
ASCII precision (number of digits) and binary byte order (normal or swapped).
format.asciiprecision
Attribute The precision (number of digits) for all numbers printed with the ASCII format.
Default 6
TSP-Link
accessibility
This attribute cannot be accessed from a remote TSP-Link node.
Usage precision = format.asciiprecision -- Reads precision.
format.asciiprecision = precision -- Writes precision.
precision Set from 1 to 16.
Remarks • This attribute selects the precision (number of digits) for data printed with the print,
printnumber and printbuffer functions. The precision attribute is only used with the ASCII
format. The precision must be a number between 1 and 16.
• Note that the precision is the number of significant digits printed. There will always be one digit to
the left of the decimal point. Be sure to include this digit when setting the precision.
• The default (reset) precision is 6.
Also see format.byteorder, format.data, printbuffer, printnumber
Example Sets the ASCII precision to 7 digits and prints a number:
format.asciiprecision = 7
print(2.5)
Output: 2.500000E+00
format.byteorder
Attribute The binary byte order for data printed using the printnumber and printbuffer functions.
Default format.SWAPPED
TSP-Link
accessibility
This attribute cannot be accessed from a remote TSP-Link node.
Usage order = format.byteorder -- Reads byte order.
format.byteorder = order -- Writes byte order.
Set order to one of the following values:
0 or format.NORMAL Most significant byte first.
0 or format.BIGENDIAN Most significant byte first.
0 or format.NETWORK Most significant byte first.
1 or format.SWAPPED Least significant byte first.
1 or format.LITTLEENDIAN Least significant byte first.
Remarks • This attribute selects the byte order that data is written when printing data values with the
printnumber and the printbuffer functions. The byte order attribute is only used with the
SREAL, REAL, REAL32, and REAL64 data formats.
• NORMAL, BIGENDIAN, and NETWORK select the same byte order. SWAPPED and
LITTLEENDIAN select the same byte order. They are alternative identifiers. Selecting which to
use is a matter of preference.
• Select the SWAPPED or LITTLEENDIAN byte order when sending data to an IBM PC compatible
computer.
Also see format.asciiprecision, format.data, printbuffer, printnumber
Example Selects the SWAPPED byte order:
format.byteorder = format.SWAPPED
