The number of decimal places in the results can be increased or decreased by setting the value for 'Significant figures' (from 6 through 9). Input values may be in the range 360° 0' 0" through 360° 0' 0" for degrees and the equivalent for radians (thus 2π through 2π). To perform an addition, e.g., 3.5 radians plus 2.5 radians, enter the 1st and 2nd values into the left and right 'radian' textboxes and click on '+'. (The result appears in the left 'radians' textbox.) The addition (and subtraction) of angles is performed modulo 2π, as shown in the example below, where adding 4.5 to 3.5 produces 1.716815 (which is 8  2π). Subtraction is performed similarly, e.g., 1.716815  4.5 gives 3.5.
When the 'Round to minutes' checkbox is checked, the result in degrees is rounded to the nearest minute. When the 'Output in decimal' checkbox is checked, the result is given either in (a) decimal degrees or (b) degrees and decimal minutes. An input radian value may be negative. To input a negative degrees value, enter the value and click on the 'Change sign' button. All this is illustrated in the results shown below:
To convert decimal degrees (plus optionally decimal minutes and decimal seconds) into degrees, minutes and seconds, enter the degrees value and click on the 'Degrees to radians' button, then click on the 'Radians to degrees' button, as illustrated in the results shown below:
To convert decimal degrees into degrees plus decimal minutes, or viceversa, enter the degrees value and click on the 'Degrees to radians' button, then click on the 'Radians to degrees' button, as illustrated in the results shown below. Make sure that the 'Output in decimal' checkbox is checked, and the decimal degrees/minutes selection is appropriate.
The 'arrow' button may used to transfer the value in the left textbox to the rightbox, if needed.
Addition and subtraction of angle values may be performed as follows:
These four operations are illustrated by the results shown below:
As noted above, addition and subtraction of angles is performed modulo 2π.
