enter the denominator. See Example 28.
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

z To convert between a decimal and fractional result, press [ 2nd ]
[ F D ] and [ ]. See Example 30.
z Calculations containing both fractions and decimals are calculated
in decimal format. See Example 31.
Angle Unit Conversion
z 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°=πrad = 200 grad
Angle conversations ( 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), ″ (seconds), r (radians), g
(gradians) or DMS (Degrees-Minutes-Seconds).
4. Choose the units you are converting from.
5. Press [ ] twice.
z To convert an angle to DMS notation, select "DMS " which
converts an entry to DMS notations, i.e., where 1°30′0″
represents 1 degrees, 30 minutes, 0 seconds. See Example 33.
z To convert a DMS notation to decimal, select °(degrees), ′
(minutes), ″ (seconds). See Example 34.
