Hi,

When converting a `xsd:double` to `xsd:decimal`, the `xsd:decimal` value keeps the E notation (which seems invalid : [XML Schema Part 2: Datatypes Second Edition](https://www.w3.org/TR/xmlschema-2/#decimal) )

Is this a bug?  
And does someone if there’s a workaround?

Query:

```auto
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
SELECT * WHERE {
  BIND( "1.62608E7"^^xsd:double AS ?value_double ) .
  BIND( xsd:decimal(?value_double) AS ?value_decimal ) .
}

```

returns:  
?value\_double: "1.62608E7"^^xsd:double  
?value\_decimal: "1.62608E7"^^xsd:decimal

Update: Forgot to mention the Stardog Version:  
Stardog Server Version: 7.9.1

Regards  
Michael

Hi Michael,

This looks like a bug. I created a ticket for it: [PLAT-5145].

Thanks,  
Lars
