[jira] [Commented] (MATH-809) Expressions and functions interpreter

    [ https://issues.apache.org/jira/browse/MATH-809?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13408009#comment-13408009 ] 

Guillaume Chauvet commented on MATH-809:
----------------------------------------

Thank you for your explanations, Gilles. I think it's possible to provide an alternative implementation without frontend by implementing the interpreter design pattern (to keeping goal of commons-math).
I will send a mail to dev list to discuss about this potential new feature.

> Expressions and functions interpreter forked from exp4j library (http://projects.congrace.de/exp4j, an Apache 2 project). This implementation use Dijkstra's Shunting Yard Algorithm. The patch also allows parsing of E notation numbers in expressions.
