<p>There is a bug in an edge case in #truncated primitive in 64 bits Cog Spur (tested on Linux, both in Cuis and Squeak). It is when #truncated a Float that is slightly larger than SmallInteger maxVal.<br>
SmallInteger maxVal   -->  1152921504606846975</p>
<p>If we take (1152921504606846975.0 predecessor), to ensure a Float that still fits in a SmallInteger, everything works fine:<br>
1152921504606846975.0 predecessor asTrueFraction   -->  1152921504606846848<br>
1152921504606846975.0 predecessor asTrueFraction   -->  class SmallInteger<br>
1152921504606846975.0 predecessor truncated   -->  1152921504606846848</p>
<p>But taking 1152921504606846976.0:<br>
1152921504606846976.0 asTrueFraction   -->  1152921504606846976 (correct result)<br>
1152921504606846976.0 asTrueFraction class   -->  LargePositiveInteger (ok. Doesn't fit in SmallInteger)<br>
1152921504606846976.0 truncated   -->  -1152921504606846976<br>
The primitive is answering SmallInteger minVal, (a negative number!) but it should fail, as the correct result doesn't fit in a SmallInteger.</p>
