Get rotation from a vector?

Hi, let's say I've got an image and a vector ([0.4,0.6] for example) that i'm moving the image along. How can I get the angle that the image needs to be rotated to point in the vectors direction? Must be something with sinus and cosinus but I can't figure out the correct formula. Maybe you can help me? |

atan(.6/.4) will return the angle for the above example. |
| ||
Ang=Atan2(x,y) |
| ||
Ang=Atan2(x,y) y,x. |
| ||
y,x |

Thanks all! Didn't even know about this command. |
