Radian-Degree Calculator is a Windows software for:
1. converting radians to and from degrees, minutes and seconds
2. converting decimal degrees to and from degrees, minutes and seconds,
3. converting decimal degrees to and from degrees and decimal minutes, and
4. performing addition and subtraction of angles

Radian-Degree Calculator is a software for converting radians to and from degrees, minutes and seconds, and for performing addition and subtraction of angles. Input values must be in the range -360? 0' 0" through 360? 0' 0" for degrees and the equivalent for radians (thus -2?? through 2??). Addition and subtraction of angles is modulo 2??, as shown in the second conversion/addition in the example above. The number of decimal places in the results can be increased or decreased by setting the value for 'Significant figures'.
