Technical Information
Degree, Minute, Second (Sexagesimal) 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}{Minutes}{Seconds}
Note that you must always input something for the degrees and minutes, even if they are zero.
Example: Input 2°0’30”
- 2030
- 2°0°30.
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 1: 2°20’30” + 39’30”
- 2203003930
- 3°0°0.
Example 2: 12°34’56” × 3.45
- 123456345
- 43°24°31.2
Converting Values between Sexagesimal and Decimal
Example: To convert the decimal value 2.258 to a sexagesimal value and then back to a decimal value
- 2258
- 2.258
- (←)
- 2°15°28.8
- 2.258
