    Break down angle to 360 degrees

    Hi, i have an angle that can range from - 10000 to 10000 and could like to know what angle its on in a 0 - 360 spectrum.

    Eg. 1145 would equal 65
    -20 would equal 340

    Cheers

    Just subtract 360 from the original angle until it is between 0 and 360. For example:

    1145 - 360 = 785
    785 - 360 = 425
    425 - 360 = 65

    *Edit* or add if it is negative. For example

    -20 + 360 = 340

    It's really late, but the basic formula is going to be something like

    for x > 360, take the remainder of x/360.

    400, for example. 400/360 is 1 (throw that away) with a remainder of 40, or think of it as 40 degrees past one full circle.

    For x < 0 ....
    take x + (360+360*INT(x/360))
    meaning -20 gives
    -20 + 360 + 0, or 340.

    -400 gives us
    -400 + 360 + (360*1) or 720 - 400 = 320.

    Double check that, but it looks close.
