Percent Calculations
Inputting a value and pressing
1((%) causes the input value to become
a percent.
150
× 20% = 30
150 * 20 1((%)= 30
Calculate what percentage of 880 is 660. (75%)
660 / 880 1((%)= 75
Increase 2500 by 15%. (2875)
2500 + 2500 * 15 1((%)= 2875
Discount 3500 by 25%. (2625)
3500 - 3500 * 25 1((%)= 2625
Degree, Minute, Second (Sexagesimal) Calculations
Performing an addition or subtraction operation between sexagesimal values,
or a multiplication or division operation between a sexagesimal value and a
decimal value will cause the result to be displayed as a sexagesimal value.
You also can convert between sexagesimal and decimal. The following
is the input format for a sexagesimal value: {degrees}
$ {minutes} $
{seconds} $.
Note: You must always input something for the degrees and minutes, even
if they are zero.
2°20´30˝ + 39´30˝ = 3°00´00˝
2 $ 20 $ 30 $+ 0 $ 39 $ 30 $= 3°0´0˝
Convert 2°15´18˝ to its decimal equivalent.
2 $ 15 $ 18 $= 2°15´18˝
(Converts sexagesimal to decimal.) $ 2.255
(Converts decimal to sexagesimal.) $ 2°15´18˝
