What does this PR do?
These changes add a SQL square root function
sqrt().Practically, this is function is based on the
abs()function. Furthermore, square roots of negative numbers return null, to avoid an error.Motivation
I think, this function is useful as it is one of the very few math functions
in the Enterprise Java Beans Query Language (EJB-QL).
