The Arithmetic Function block lets you use a function or procedure as a block in a
diagram. The block applies the function or procedure to its input value and passes
the result. Specify the name of the function in the attribute Arithmetic Function.

two values:

User-Defined Function
You may use any user-defined function that accepts one quantitative argument
and returns one quantitative value. Set the attribute Arithmetic Function to the
name of the function. This figure shows a diagram that figures the factorial of a
value:

Procedure
You can use a procedure that accepts three arguments, described in the following
table, and returns a single value. Set the attribute Arithmetic Function to the name
of your procedure. The block passes the procedure's return value as its output
value. The block automatically passes the Collection-time and Quality of the
block's input data path.
| Argument | Type | Description |
|---|---|---|
|
value
|
The block's input value.
|
|
float
|
The Collection-time of the block's input path.
|
|
symbol
|
The Quality of the block's input path.

Tabular Function
You can use a tabular-function-of-1-arg that accepts one argument and returns a
value. Set the attribute Arithmetic Function to the name of your function. The
block passes its input value to the function as an argument and passes the function's return value as its output value. If the function cannot evaluate the input
value, NOL signals an error. For information on a G2 tabular-function-of-1-arg, see
the G2 Reference Manual.
