Calculations
t'ou con perform calculations using sexagesimal
values,and convert values between sexagesimal
and decimal.
Inputting Sexagesimal Values
The following is the syntax for inputting a
sexagesimal value

■ Note that you must always input something for the
degrees and minutes, even if they are zero.
Sexagesimal Calculations
• Performing the following types of sexagesimal
calculations produces a sexagesimal result.
■Addition or subtraction of two sexagesimal values
-Multiplication or division of a sexagesimal value
and a decimal value

Using Multi-statements in Calcu ations
You can use the colon character (:) to connect two or
more expressions and execute them in sequence
fram left to right when you pressS .
Example: Ta create a multi-statement that perfarms
the following two calculations: 3+-3 and 3><3
njNEI

"Disp" indicates this is an intermediate result of a
multi-statement.

Using Calculation History
Memory and Replay (COMP)
Calculatian history memory maintains a record of
each calculation expression you input and execute,
and its result.
You can use calculation history memory in the
COMP Mode(rMoBHCD)only.___________________
