             Summary: fn:ceiling does not work on xs:decimal
                 Key: DAFFODIL-2076
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2076
             Project: Daffodil
          Issue Type: Bug
          Components: Back End
    Affects Versions: 2.3.0
            Reporter: Steve Lawrence
             Fix For: 2.4.0


The fn:ceiling function (and likely other related functions that do rounding-like operations) does not correctly work on xs:decimal's. For example:
{code}
fn:ceiling(xs:decimal(0.125))
{code}
results in 0.125. The expected value is 1.

Floats and doubles do round correctly, so a temporary work around is to cast any decimals that are passed into fn:ceiling to xs:doubles.

Note that commit a20ff4172807f5e0264ce68142f15f9798df1e8b changed the behavior of {{div}} to always return an xs:decimal instead of an xs:float/double, so any functions that try to fn:ceiling a division will likely run into this issue and require the xs:double cast as a workaround.
