If you want to perform those operations, then you will run into issues like rounding. If you need to perform those operations, you could write a custom expressions using java bigdecimal that can perform those operations and give you back number as text<div style="clear:both;"></div>https://community.appian.com/thread/15827?ContentTypeID=1Thu, 05 Mar 2015 13:41:21 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:57919de1-4973-43c7-bbfa-48eb507ee95bPhilBAs Stefan said, for very large numbers you must use a text field; it&#39;s worth having a look at the regular expressions plugin as you&#39;ll need to validate the inputs to the text field.<div style="clear:both;"></div>https://community.appian.com/thread/15826?ContentTypeID=1Thu, 05 Mar 2015 13:21:49 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:675d25a6-6de1-4f0f-b331-55af60890ca7kumara0002Use a!textField(label:&quot;Amount&quot;,value:local!variable,saveInto:ri!desiredvariable &lt;&lt;todecimal(local!variable)) .Before saving convert it into your desired data type which you have in the database.<div style="clear:both;"></div>https://community.appian.com/thread/15825?ContentTypeID=1Thu, 05 Mar 2015 13:19:45 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:d35b94bc-4b85-456a-8a78-8f6699c6c45eStefan HelzleYou these large numbers you have to use a variable of type text and a text field.
