ESQL: Warn about division (#109716)
When you divide two integers or two longs we round towards 0. Like
Postgres or Java or Rust or C. Other systems, like MySQL or SPL or
Javascript or Python always produce a floating point number. We should
warn folks about this. It's genuinely unexpected for some folks. OTOH,
converting into a floating point number would be unexpected for other
folks. Oh well, let's document what we've got.

The files in these subdirectories are generated by ESQL's test suite:

  • description - description of each function scraped from @FunctionInfo#description
  • examples - examples of each function scraped from @FunctionInfo#examples
  • parameters - description of each function's parameters scraped from @Param
  • signature - railroad diagram of the syntax to invoke each function
  • types - a table of each combination of support type for each parameter. These are generated from tests.
  • layout - a fully generated description for each function
  • kibana/definition - function definitions for kibana's ESQL editor
  • kibana/docs - the inline docs for kibana

Most functions can use the generated docs generated in the layout directory. If we need something more custom for the function we can make a file in this directory that can include:: any parts of the files above.

To regenerate the files for a function run its tests using gradle:

./gradlew :x-pack:plugin:esql:test -Dtests.class='*SinTests'

To regenerate the files for all functions run all of ESQL's tests using gradle:

./gradlew :x-pack:plugin:esql:test
