     Notice, that all operations on fractions reduce their result; this means, that
     the result of a fraction-operation may return an integer.
     Aka:
-	(1 / 7) * 7   ->  1  (not 0.99999999...)
+        (1 / 7) * 7   ->  1  (not 0.99999999...)
 
     Mixed mode arithmetic:
-	fraction op fraction    -> fraction/integer
-	fraction op fix         -> fix; scale is fix's scale
-	fraction op integer     -> fraction/integer
-	fraction op float       -> float
+        fraction op fraction    -> fraction/integer
+        fraction op fix         -> fix; scale is fix's scale
+        fraction op integer     -> fraction/integer
+        fraction op float       -> float
