Rinciog Octavian updated MARMOTTA-627:
--------------------------------------
Description:
Hy,
I'm trying to calculate some distances and I need to make some arithmetic
operations with some numbers 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.
Other examples:
SELECT (0.1*0.1 as ?c) WHERE {} => 1.00
SELECT ( 0.10*0.01 as ?c) WHERE {} => 10.0
SELECT ( 1.00*3.10 as ?c) WHERE {} => 0.32258064516129032258
SELECT ( 2.00*4.00 as ?c) WHERE {} => 0.500
Thank you,
was:
