CF uses java.lang.Doubles for its floating point numbers:

Note that there is a precisionEvaluate function that internally uses BigDecimal.

Maybe that's why my 15 digit long decimal is cutting to 12?

Thanks for you reply.

Just 12? Is your 15 digit decimal perhaps being truncated by some other process? Restriction by a function or by the display field? Database field length?  the following displays 20 decimals (in CF9.0.1 at least):

<cfset x = 0.12345678901234567890>
<cfoutput>#x#</cfoutput>

Hello,

Yes, something else was truncating my decimals.

Thanks all for your help.

CF also has a method called PrecisionEvaluate that uses Java's BigDecimal. So for higher precision requirement, it is a handy function.
