prassee / exp4S

a Scala wrapper around Exp4j library

Exp4s

Scala wrapper around Exp4j library. This is still under-development and more features to come. Read more about exp4j.

Maven co-ordinates / download

Exp4s is hosted only my personal github maintained repo server. Please find the below co-ordinates to usage.

current version 0.0.4

//moma -> my own maven archive :)
resolvers ++= Seq("moma" at "https://github.com/prassee/moma/raw/master/snapshots")
libraryDependencies ++= Seq("me.prassee" %% "exp4s" % "<current_version>")

Usage

  import Exp4sProcessor._

Step 2

  // a more idomatic way of doing
  // pass the formula , the variables followed by the values
  val x = forFormula("(sqrt(a^2) + sqrt(b^2))")("a", "b")(1, 2)
  println(x)

Step3

  // shortcut and simplified one  - formula followed by "with" keyword and variables and values as next set of params
  val compiledForm: Double = compileFormula("(sqrt(a^2) + sqrt(b^2)) with a,b", 1, 2)
  println(compiledForm)

@TODO

• support for custom functions
• support for async formula execution
