Use number signs in expressions only when necessary, because unneeded number signs reduce clarity and can increase processing time. The following example shows the preferred method for referencing variables:
<cfset SomeVar = Var1 + Max(Var2, 10 * Var3) + Var4>
In contrast, the following example uses number signs unnecessarily and is less efficient than the previous statement:
<cfset #SomeVar# = #Var1# + #Max(Var2, 10 * Var3)# + #Var4#>
