infix-rationals

Installation

npm install infix-rationals infix rationals

This package ties together the rational number implementation in rationals and the infix arithmetic implementation in infix.

Functionality

Given ir = require('infix-rationals') and r = require('rationals'):

• ir.numberProvider: This object works as a number provider for infix.

• ir.evaluate: Use to evaluate arithmetic expressions with rational numbers, for example

   console.log(ir.evaluate("10/(2+3)").display());
   // `2` has now been logged
  

• ir.compile: Use to compile arithmetic expressions, for example

   var f = ir.compile("10/($0+3)");
   f(r(1));
   f(r(1,2));
   f(r(3));
  

• ir.memCompile: Use as compile above. This version caches the compiled version of all given expressions, it is memoizing.

This gives an overview of what is available. For further details, please see the documentation of both the infix and rationals packages.
