DEG (Function)

is a function which takes a number representing an angle measured in radians, and gives a result which is the angle measured in degrees.

is interesting in that it exposes that Petit Computer implements more sophisticated calculations "behind the scenes" than can be achieved directly. For example,  gives , very close to the true value 521391.593569 (in fact, it is as close as you can get with the fixed-point values used in Petit Computer). Calculating  gives an error , whereas calculating   gives  , which is off by about 39.
