<PRE><B>Question 1150890</B>
.


OK, &amp;nbsp;I see that after my note, &amp;nbsp;you made a progress in half-step.


My next question is:  &amp;nbsp;What is  &amp;nbsp;&quot;O.8&quot; &amp;nbsp;in your post ?


Does it mean &quot;0.8&quot; ?



Do you distinct &amp;nbsp;0 &amp;nbsp;(zero) &amp;nbsp;and &amp;nbsp;&quot;capital &amp;nbsp;O&quot; &amp;nbsp;?

&lt;U&gt;Comment from student&lt;/U&gt; : &amp;nbsp;&amp;nbsp;oh sorry, &amp;nbsp;O.B was actually &amp;nbsp;0.8.

&lt;U&gt;My response&lt;/U&gt; : &amp;nbsp;&amp;nbsp;O-o-o (!)  &amp;nbsp;&amp;nbsp;It is just much better.
