Rinciog Octavian updated MARMOTTA-627:
--------------------------------------
Description:
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 {}
returns 1.00
Thank you,
