User-defined Functions

ClassPad lets you configure calculation operations as user-defined functions, which can then be used inside 
of numeric expressions just like its built-in functions. User-defined functions can also be called up in other 
applications.

Note

• User-defined functions are stored in ClassPad memory as “FUNC” (Function) type variables. Naming, 

storage, and folder rules are identical to those for user variables.

• A user-defined function can contain only a single mathematical expression. 

• A user-defined function cannot contain any command.

 Creating a New User-defined Function

You can use either of the methods below to create user-defined functions.

• Using the Program application’s Program Editor window.

• Using the Main application’s Define command.

 

u

To create and save a new user-defined function using the Program Editor window

Example:

  To create a user-defined function named “f4” that calculates the following: 

x

 

×

 (

x

 + 1) 

×

 (

x

 – 2)

1. On the Program Loader or Program Editor window, tap 

O

.

2. On the dialog box that appears, configure the settings for the new file as described below.

• Tap the [Type] down arrow button and then select “Function”.

• Tap the [Folder] down arrow button and then select the folder where you want to save the user-defined 

function.

• In the [Name] box, input up to eight bytes for the user-defined function name. Here, we will input “f4”.

3. Tap [OK]. This displays a blank Program Editor window.

4. Input user-defined function arguments into the parameter variable box. Here, 

we will input “

x

”.

5. Input the expression you want. Here, we will input “

x

 

×

 (

x

 + 1) 

×

 (

x

 – 2)”.

6. After the function is the way you want, tap 

{

, or tap [Edit], [Save File] and 

then [Save] to save it.

 

u

 To create a user-defined function using the Define command

Example:

  To create a user-defined function named “f2” that calculates the following: 

2

x

 + 3

y

 + 1

1. On the Program Loader window, tap 

~

, or tap 

O

, [Window] and then [Main] to display the Main application 

window.

• You could also tap 

M

 on the icon panel to start up the Main application.

2. Tap [Interactive] and then [Define].

3. On the dialog box that appears, input the following.

• [Func name]: “f2”

• [Variable/s]:  “

x

, 

y

”

• [Expression]:  2

x

 + 3

y

 + 1
