   The Gamma Function by R. A. Askey and R. Roy
  </div>
  <hr/>
<p>
The Gamma function is an extension of the factorial function to 
real and complex numbers. For positive integers, 
<m:math display="inline">
 <m:mi mathvariant="normal">&#x0393;</m:mi>
 <m:mrow>
  <m:mo>(</m:mo>
  <m:mi>n</m:mi>
  <m:mo>)</m:mo>
 </m:mrow>
 <m:mo>=</m:mo>
 <m:mrow>
  <m:mo>(</m:mo>
  <m:mi>n</m:mi>
  <m:mo>-</m:mo>
  <m:mn>1</m:mn>
  <m:mo>)</m:mo>
  <m:mi mathvariant="normal">!</m:mi>
 </m:mrow>
</m:math>.
</p>

These pages explore Axiom's facilities for handling the Gamma function.
In particular we try to show that Axiom conforms to published standards.
