• In the Math input/output mode, the operation to recall answer memory contents is different
from the operation in the Linear input/output mode. For details, see “History Function” (page
1-17).
• Performing an operation that assigns a value to an Alpha memory (such as
faal(B) w), answer memory contents are updated in the Math input/output mode
but not in the Linear input/output mode.
k Performing Continuous Calculations
Answer memory also lets you use the result of one calculation as one of the arguments in the
next calculation.
Example 1 ÷ 3 =
1 ÷ 3 × 3 =
Ab/dw
(Continuing) *dw
Continuous calculations can also be used with Type B functions (

3. Specifying the Angle Unit and Display Format
Before performing a calculation for the first time, you should use the Setup screen to specify
the angle unit and display format.
k Setting the Angle Unit [SET UP] - [Angle]
1. On the Setup screen, highlight “Angle”.
2. Press the function key for the angle unit you want to specify, then press J.
• { Deg } / { Rad } / { Gra } ... {degrees}/{radians}/{grads}
• The relationship between degrees, grads, and radians is shown below.
360° = 2 π radians = 400 grads
90° = π /2 radians = 100 grads
k Setting the Display Format [SET UP] - [Display]
1. On the Setup screen, highlight “Display”.
2. Press the function key for the item you want to set, then press J.
• { Fix } / { Sci } / { Norm } / { Eng } ... {fixed number of decimal places specification}/
{number of significant digits specification}/{normal display}/{Engineering mode}
