Solr 7.3 has very sophisticated math capabilities described below: https://github.com/joel-bernstein/lucene-solr/blob/math_expressions_documentation/solr/solr-ref-guide/src/math-expressions.adoc
This is the userguide for math expressions which didn't make the 7.3 release but all the functions are committed and working for 7.3. It's only the documentation that is lagging behind. About 30 new functions are added with every release.
