Example

<h3>BitSHLN Example</h3>
<p>Returns the number, bitwise shifted, without rotation, to the left by count bits.</p>

<p>BitSHLN(1,1): <cfoutput>#BitSHLN(1,1)#</cfoutput></p>
<p>BitSHLN(1,30): <cfoutput>#BitSHLN(1,30)#</cfoutput></p>
<p>BitSHLN(1,31): <cfoutput>#BitSHLN(1,31)#</cfoutput></p>
<p>BitSHLN(2,31): <cfoutput>#BitSHLN(2,31)#</cfoutput></p>

Example
