1-24 Getting started
HINT When you retrieve a number from ANS, you obtain the
result to its full precision. When you retrieve a number
from the HOME’s display history, you obtain exactly what
was displayed.
Pressing evaluates (or re-evaluates) the last input,
whereas pressing
ANS copies the last result (as ANS)
into the edit line.
Storing a value
in a variable
You can save an answer in a variable and use the
variable in later calculations. There are 27 variables
available for storing real values. These are A to Z and θ.
See Chapter 14, “Variables and memory management”
for more information on variables. For example:
1. Perform a calculation.
45 8 3
2. Store the result in the A variable.
A
3. Perform another calculation using the A variable.
