format.data
This attribute sets the data format for data that is printed using the printnumber() and printbuffer()
functions.
Type TSP-Link accessible Affected by Where saved Default value
Instrument reset
Usage
value = format.data
format.data = value
The format to use for data, set to one of the following values:
ASCII format: format.ASCII
Single-precision IEEE Std 754 binary format: format.REAL32
Double-precision IEEE Std 754 binary format: format.REAL64
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 t
he
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)
Output a number represented by x in ASCII
using a precision of 10, then output the same
number in binary using double precision
format.
Output:
3.141592650e+00
