title: How to convert Hex string to Decimal
body: <p>When I try this,</p>
  
  <pre><code>Decimal m = Decimal.Parse(columns[1], System.Globalization.NumberStyles.AllowHexSpecifier);
  </code></pre>
  
  <p>I get an ArgumentException saying this,</p>
  
  <blockquote>
    <p>The number style AllowHexSpecifier is not supported on floating point
    data types.</p>
  </blockquote>
  
  <p>and columns[1] = 4B414D000000011613C3 btw.</p>
  
  <p>what am I doing wrong and how do I fix it ?</p>
