There are size and length constraints for float (4 bytes, 7 digits) and double (8 bytes, 15-16 digits). Length does not need to be mentioned in this case. The column in the database also needs to be of the same name and datatype.</p> <p>Here is how it should look like:</p> <p>&lt;xsd:element name=&quot;remunerationAmount&quot; nillable=&quot;true&quot; type=&quot;xsd:double&quot;&gt;<br />&lt;xsd:annotation&gt;<br /> &lt;xsd:appinfo source=&quot;appian.jpa&quot;&gt;@Column(name=&quot;remunerationAmount&quot;, columnDefinition=&quot;DOUBLE&quot;)&lt;/xsd:appinfo&gt;<br /> &lt;/xsd:annotation&gt;<br /> &lt;/xsd:element&gt;</p><div style="clear:both;"></div>
