DEDICACE

Type:

Function

 

Description:

Displays a greeting from the CAS team and dedication to all HP calculator users.

Access:

Catalog, …µ

 

Example:

In algebraic mode, the message can be extended. Try: DEDICACE(Salutations)

 

 

 

DEF

 

 

Type:

Function

 

Description:

Defines a variable or a function. Works like the DEFINE command, except that it returns a result

 

and can be included in an algebraic expression. Given an expression as input, DEF stores the

 

expression, unlike STORE which evaluates the expression and stores the numerical value.

Access:

Catalog, …µ

 

Input:

Level 1/Argument 1: An expression of the form

 

name=expression or

 

 

name(name1, … namen)=expression(name1,… name n)

 

In the first case, name is the name of a variable, and expression is an expression or a number to be

 

stored in the variable. If the variable does not exist, it is created in the current directory. In the

 

second case, name is the name of a variable that will be treated as a function, name1 to namen are

 

formal variables used to define inputs the function will take.

Output:

Level 1/Item 1: Unlike DEFINE, which returns NOVAL in Algebraic mode, and no result in

 

RPN mode, DEF returns the expression used as the input.

Flags:

Exact mode must be set (flag –105 clear).

 

Numeric mode must not be set (flag –3 clear).

Example 1:

Define a new function that calculates:

 

 

(a-b)/(a+b)

 

Command:

DEF(NEW(A,B)=(A-B)/(A+B))

 

Result:

NEW(A,B)=(A-B)/(A+B)

 

Example 2:

Check that the newly defined function works:

Command:

NEW(2,1)

 

Result:

1/3

Command

 

Type:

 

Description:

Define Variable or Function Command: Stores the expression on the right side of the = in the

 

variable specified on the left side, or creates a user-defined function.

 

If the left side of the equation is name only, DEFINE stores exp in the variable name.

 

If the left side of the equation is name followed by parenthetical arguments name1 … namen,

 

DEFINE creates a user-defined function and stores it in the variable name.
