z
To enter a mixed number, enter the integer part, press [ A
b
/
c
],
enter the numerator, press [ A
b
/
c
], and enter the denominator ; To
enter an improper fraction, enter the numerator, press [ A
b
/
c
], and
enter the denominator. See Example 24.
z
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 [ ] ) or the [ = ] key. By pressing [ 2nd ] [ A
b/c d/e ], the displayed value will be converted to the improper
fraction and vice versa. See Example 25.
z
To convert between a decimal and fractional result, press [ 2nd ]
[ F
D ] and [ ENTER ]. See Example 26.
z
Calculations containing both fractions and decimals are calculated
in decimal format. See Example 27.

Angle Unit Conversion
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
°
=
π
rad = 200 grad
Angle conversations ( See Example 28. ) :
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),
″
(seconds), r (radians), g
(gradians) or
f
DMS (Degrees-Minutes-Seconds).
4. Choose the units you are converting from.
5. Press [ ENTER ] twice.
z
To convert an angle to DMS notation, select “
f
DMS
” which
converts an entry to DMS notations, i.e., where
1
°
30
′
0
″
represents 1 degrees, 30 minutes, 0 seconds. See Example 29.
z
To convert a DMS notation to decimal, select
°
(degrees),
′
(minutes),
″
(seconds). See Example 30.
