function FixD(Degrees: Extended): Extended;
Source
function FixD(Degrees: Extended): Extended; var t: Integer; begin if Degrees < 0 then t := -1 else t := 1; Result := Abs(Degrees); Result := (Floor(Result) mod 360 + DecRet(Result)) * t; if Result < 0 then Inc(Result, 360); end;

Description
Fixes an angle specified by Degrees in degrees by adding/subtracting 360 until the value is larger than or equals 0 and is smaller than or equals 360.
Example
begin WriteLn(FixD(25)); WriteLn(FixD(385)); end.
Output:
25 25
