-------------------------------------------------
Hi [~xvade] , Yes, trunk is where I look at.
Over the weekend cassandra-4.1 and new trunk branches were created and I
suspect this made some mess with your branch. If you check it - the last commit
is some huge merge commit. Your own commits are somewhere in between the trunk
commits.
You should have trunk and last on top of everything else - your own commits.
Please let me know if you need any help.
> Add Math functions
> -------------------
>
> Key: CASSANDRA-17221
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17221
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL/Syntax
> Reporter: Benjamin Lerer
> Assignee: Simon Chess
> Priority: Normal
> Labels: AdventCalendar2021, lhf
> Fix For: 4.x
>
>
> We should add native Maths functions for the most common operations:
> * {{abs\(x)}} returns the absolute value of the x
> * {{exp\(x)}} returns the value of e (the base of natural logarithms) raised
> to the power of x
> * {{log\(x)}} returns the natural logarithm (base e) of x
> * {{log10\(x)}} returns the base-10 logarithm of x
> * {{round\(x)}} returns the closest integer to x
> +Additional information for newcomers:+
> The new functions should be put in a new class {{MathFcts}} similar to
> {{TimeFcts}}.
> The {{MathsFcts.all()}} method should be called in
> {{SystemKeyspace.functions}}
> The unit tests for the functions should be put in a {{MathFctsTest}} similar
> to {{TimeFctsTest}}
