Signed number representations in verilog
<ol>
<li>What methods exist for signed number representation?</li>
<li>How do you know which signed number representation is used for the application?</li>
</ol>

<p>e.g. </p>

<p>IEEE 754 allows you to represent 1.3444E-15  and  1.3444E+15... implying very large number &amp; a very small number simply based on 1 signed representation of exponent.  IEEE 754 exponent <a href="http://www.slideshare.net/prochwani95/06-floating-point" rel="nofollow noreferrer">field uses <em>biased exponent representation</em></a> see page 7. Similarly , which other methods exist. </p>
