Hy,

I'm trying to calculate some distances and I need to make some arithmetic 
operations with number below 1.

Unfortunately, this kind of operation seems not to work with the latest version 
of Apache Marmotta (I'm using Apache Marmotta built from repo).

For example, the following query returns -39.5!!!!

SELECT  (  (4.5-4.4)*0.1 as ?c) 
WHERE {}

I've tried many combinations with xsd:decimal, xsd:float, xsd:double, but the 
answer is or 1.000 or -39.5.

Another example: 

SELECT  (0.1*0.1 as ?c) 
WHERE {}

return 1.00

Thank you,
