Section 8: TSP command reference

format.data

This attribute sets the data format for data that is printed using the printnumber() and printbuffer()
functions.
Type TSP-Link accessible
Attribute (RW) No
Usage

Details
You can control the precision of numeric values with the format.asciiprecision attribute. If
format.REAL32 or format.REAL64 is selected, you can select the byte order with the
format.byteorder attribute.
The IEEE Std 754 binary formats use four bytes for single-precision values and eight bytes 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.
Example
format.asciiprecision = 10
x = 3.14159265
format.data = format.ASCII
printnumber(x)
format.data = format.REAL64
printnumber(x)
