Average loop length: Difference between revisions

This is about the limit of what you can do with uBasic/4tH. Since it is an integer BASIC, it uses what has become known in the Forth community as "Brodie math". The last 14 bits of an 64-bit integer are used to represent the fraction, so basically it is form of "fixed point math". This, of course, leads inevitably to rounding errors. After step 14 the number is too large to fit in a 64-bit integer - so at that point it simply breaks down. Performance is another issue.
