asterisk in arithmetic output
<p>When computing 2 doubles, 1/81 on the android platform, 0.01234567* was returned. What does the asterisk mean and how can I avoid such an output?</p>

<pre><code>a=Double.parseDouble(subexp.substring(ss, i));
b=Double.parseDouble(subexp.substring(i+1, se+1));

subexp=subexp.substring(0,ss).concat(Double.toString(a/b))
.concat(subexp.substring(se+1,subexp.length()));
</code></pre>

<p>so basically the piece of offending code is above, with the following values grabbed from the debugger:</p>

<pre><code>subexp="1+1/81" (before code)
"1+0.01234567*" (after code) 

ss=2, se=5, i=3, a=1.0, b=81.0
</code></pre>
