The syntax symbol <nrf value> refers to the flexible numeric representation defined by the GPIB
standard. It means that numbers may be represented in integer or floating point form, or in
engineering/scientific notation. The IEEE 488.2 standard uses the names NR1, NR2, and NR3
respectively to denote “integer”, “floating point”, and “scientific notation”. For example the number
“twenty” may be represented by any of the following ASCII strings:
Table 3.4 – Parameters
NR1 Integer 20 +20
NR2 Floating Point 20.0 +20.0
NR3 Scientific Notation
2.0E+1
2.0e+1 +2.0E+1
+2.0e+1
For more information on these definitions, refer to the IEEE 488.2 standard.
There are no default values for omitted parameters. If a command is expecting a parameter and
nothing is entered, an error is generated.
For further clarity in programming, the Boolean values of one (1) and zero (0) may be used. Other
acceptable names are indicated in Table 3.5. Parameters of a Boolean type are sometimes referred
to as <bool>.
