title: Which .NET data type is best for mapping the NUMBER Oracle data type in NHibernate?
body: <p>I've seen some examples in which <code>decimal</code> is used in NHibernate projects for mapping to whole number columns in Oracle. Right now I'm using <code>int</code> and <code>long</code> in my program. </p>
  
  <p>What are the advantages of <code>decimal</code> over <code>int</code>/<code>long</code>? Does it perform better?</p>
