Calculations
You can 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
{Degrees}m={Minutes} ={Seconds}mm
Example:Input 2° 0307
7 ..
22170013030) 2030
2 030”
* 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
Example: 2 20 30^-39'30'23'00'00*

Converting Values between Sexagesimal and
ecima
Pressing œ while a calculation result is displayed
oggles the value between sexagesimal and decimal.

Using Multi-statements in Calculations
You can use the colon character (:) to connect two or
more expressions and execute them in sequence
from left to right when you ргеѕѕ[=).
Example: To create a multi-statement that performs
the following two calculations: 3+3 and 3x3
LINE

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

Using Calculation History
Memory and Replay (COMP)
Calculation 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( (moe) )only.
Recalling Calculation History Memory
Contents
Pressc to back-step through calculation history
memory contents. Calculation history memory shows
both calculation expressions and results.
