페이지 인쇄• Num ber display formats are selected by pressing [ 2nd ] [ SCI/
ENG ] to display the menu. The items on the menu are FLO (for
floating point), SCI (for scientific), and ENG (for engineering).
Press [3] or [4] until the desired formats is underlined, and then
press [
]. See Example 13.
(Note) :The engineering format is similar to the scientific format,
except the mantissa can have up to three digits left of the
decimal, instead of only one, and the exponent is always a
multiple of three. It is useful for engineers to convert units
based on multiples of 10

.
• You can enter a number in mantissa and exponent form by [ EXP ]
key. See Example 14.
n Par e nt h es e s ca l cu l at i on s
• Operation inside parentheses are always executed first. AT-36
can use up to 13 levels of consecutive parentheses in a single
calculation. See Example 15.
• Closed parentheses occurring immediately before operation of the
[
] key may be omitted, no matter how many are required. See
Example 16.
• A multiplication sign " x " occurring immediately before an open
parenthesis can omitted. See Example 17.
(Note) :The calculator c an auto-correct abbreviated multiplica-
tion in front of all functions, except memory variables, left
parenthesis, type B functions.
• Henceforth, abbreviated type will not be used in this manual. See
Example 18.
• The correct result cannot be derived by entering [ ( ] 2 [ + ] 3 [ ) ]
[ EXP ] 2. Be sure to enter [ x ] 1 between the [ ) ] and [ EXP ] in
the below example. See Example 19.

• [ 2nd ] [ % ] divides the number in the display by 100. You can use
this key sequence to calculate percentages, add-ons, discounts,
and percentages ratios. See Example 20~21.
n Contin uous calcu lation fun ction
• The calculator enables you to repeat the last operation executed by
pressing [
] key for further calculation. See Example 22.
• Even if calculations are concluded with the [
obtained can be used for further calculation. See Example 23.
n An s we r f u n ct i o n
• Answer function stores the most recently c alculated result. It is
retained even after the power is turned off. Once a numeric value
or numeric expression is entered and [
is stored by this function. See Example 24.
(Note) :Even if execution of a calculation results in an error,
however, Answer memory retains its current value.

enter the denominator. See Example 28.
• During a fraction calculation, if the figure is reducible, a figure is
reduced to the lowest terms after pressing a function command key
( [ + ], [ – ], [ x ] or [

• To convert between a decimal and fractional result, press [ 2nd ]
[ F 34 D ] and [

• Calc ulations containing both fractions and decimals are calcu-
lated in decimal format. See Example 31.
n Ang le u ni ts c on v e rs io n
• The angle units (DEG, RAD, GRAD) is set by pressing [ DRG ] to
display the angle menu. The relation among the three angle units
is :
180 ° =£krad = 200 grad
Angle conversions ( See Example 32.) :
1. Change the default angle settings to the units you want
to convert to.
2. Enter the value of the unit to convert.
3. Press [ DMS ] to display the menu. The units you can
select are
(degrees), (minutes),
°
(radians),g (gradians) or 4 DMS (Degree-Minutes-
Seconds).
4. Choose the units you are converting from.
5. Press [
] twice.
• To convert an angle to DMS notation, select "4DMS ", which con-
verts an entry to DMS notations, i.e., where 1
1 degrees, 30 minutes, 0 seconds. See Example 33.
• To c onvert a DMS notation to decimal, select
(minutes),
(seconds). See Example 34.
