pnowojski commented on issue #6736: [FLINK-10398][table] Add Tanh math function
supported in Table API and SQL
URL: https://github.com/apache/flink/pull/6736#issuecomment-431023636
Ok, LGTM, I would like to merge it before 1.7 feature freeze and I didn't
see objections from @xccui so I assume that he is ok with this. (If not feel
free to open some follow up issue - documentation we can always change later,
after the feature freeze).
On a side note, I do not understand while why we have this inconsistency
between SQL and Table API. Why for Table API we are using capital case:
```
<p>Returns the tangent of <i>NUMERIC</i>.</p>
```
and for sql lower case:
```
<p>Returns the tangent of <i>numeric</i>.</p>
```
This seems strange... but I won't dive into this right now.
Again thanks for contribution @yanghua
