3-10 Full Command and Function Reference
Flags: Exact mode must be set (flag –105 clear).
Numeric mode must not be set (flag –3 clear).
Radians mode must be set (flag –17 set).
Example: Express the result of the following addition in modulo 7.
(x
2
+3x+6)+(9x+3)
Note: Before trying this example, use the CAS modes input form to set the modulo to 7.
Command: ADDTMOD(X^2+3*X+6,9*X+3)
Result: X^2-2*X+2
ADDTOREAL
Type: Command
Description: Adds specified global names to the reserved variable REALASSUME. This is a list of the global
variables that will be treated by some CAS operations as real numbers when Complex mode is set.
If a variable is already in the REALASSSUME list, this command removes any additional
assumptions made on it by ASSUME.
Access: Catalog, …µ
Input: Level 1/Item 1: The name of the global variable to be added to the REALASSUME list, or a list
of names.
Output: No output in RPN mode, NOVAL in Algebraic mode.
Flags: If the “all variables are real” flag is set (flag –128 set), ADDTOREAL will not add anything to the
REALASSUME list, as all variables are assumed real anyway. In this case it will only remove
further assumptions made by ASSUME.

ALGB
Type: Command
Description: Displays a menu or list of CAS algebraic operations.
Access: Catalog, …µ
Flags: If the CHOOSE boxes flag is clear (flag –117 clear), displays the operations as a numbered list. If
the flag is set, displays the operations as a menu of function keys.

ALOG
Type: Analytic Function
Description: Common Antilogarithm Analytic Function: Returns the common antilogarithm; that is, 10 raised
to the given power.
