Working

with user

variables

Example 2:

Create a variable called ME and assign π

2

to it.
1. Press

H

to display Home view.

2. Assign π

2

to ME:

Szj

AQAcE

3. A message appears asking if you want to create a

variable called ME. Tap

or press

E

to

confirm your intention.
You can now use that variable in subsequent
calculations: ME*3 will yield 29.6…, for example.

Example 3:

You can also store objects in variables

using the assignment operator: Name:=Object. In this
example, we’ll store {1,2,3} in the user variable YOU.
1. Assign the list to the variable using the assignment

operator:=.

2. A message appears asking if you want to create a

variable called YOU. Tap

or press

E

to

confirm your intention.
The variable YOU is created and contains the list
{1,2,3}. You can now use that variable in
subsequent calculations: For example, YOU+60 will
return {61,62,63}.

Working

with app

variables

Just as you can assign values to Home and user variables,
you can assign values to app variables. You can modify
Home settings on the

Home Settings

screen (

SH

).

But you can also modify a Home setting from Home view
by assigning a value to the variable that represents that
setting. For example, entering Base:=0

E

in Home

view forces the Home settings field

Integer

(for the

integer base) to binary. A value of 1 would force it to
octal, 2 to decimal, and 3 to hex. Another example: you
can change the angle measure setting from radians to
degrees by entering HAngle :=1

E

in Home view.
