I've got a rotation of something in degrees, however this rotation can be greater than 360 or less than 0.
How can I multiply/divide this to be within 360? For example, 1800 to be turned into 360, 900 turned into 180, etc?

3Subtract 360 till you reach the range you desire. – antman Mar 28 '15 at 10:46

Any more efficient methods? – user2722083 Mar 28 '15 at 10:47

Divide by 360 and the remainder will be your answer. – antman Mar 28 '15 at 10:49

@antman 900 divided by 360 is 2.5, which isn't correct. – user2722083 Mar 28 '15 at 10:53

3Woah! I said the remainder will be the answer. So you can't have decimal answers. You will have to use the actual division method(primary school one). – antman Mar 28 '15 at 10:55

Method 1
Subtract 360 till you reach the range you desire. (by antman from the comments)
Method 2
If programming codes can be used then the modulus operator ' % ' can be used to find the remainder.
Example:
900 % 360=180
General form:
$x$%360=[value]
Modulus operator gives the remainder when we divide the degrees by 360.
Reason
After a complete rotation (covering 360 degrees) we come back to zero.
