The 3153 uses parameters composed of decimal numbers. There are three
different formats for decimal data: NR1, NR2, and NR3. Each has two
values: one with a code and one without it. A value without a code is
regarded as a positive number. If a number exceeds the accuracy resolution
of the 3153, the value is rounded up or down.
NR1 format: Integer data
+12, -23, 34
NR2 format: Fixed point numbers
+1.23, -23.45, 3.456
NR3: Floating point number
+1.2E3, -2.3E-4, 3.4E5
The term "NRf format" includes all these three formats.
Each 3153 command designates a format.
