+#This will count the digits of a number.

+#I belive it *has* to do it faster, because it will
+#only run k times instead of n, where k=length.
+#Without having checked how str() works I expect
+#they use more loops, thus more computational time.
+#Disclaimer: it works with integers at the moment.
+#Will have to make it better in the future.
