yep, fixed. Good eye :)
> Stellar should have a better collection of basic math operations
> ----------------------------------------------------------------
>
> Key: METRON-1038
> URL: https://issues.apache.org/jira/browse/METRON-1038
> Project: Metron
> Issue Type: Improvement
> Reporter: Casey Stella
>
> At the moment the math functions are woefully incomplete.
> We should add at least the ones difficult or impossible to reconstruct using
> existing stellar primitives/math functions:
> * log10
> * log2
> * ln
> * sqrt
> * ceil
> * floor
> * sin
> * cos
> * tan
