org.jdice.calc.Properties

public class Properties
extends java.lang.Object

Properties for AbstractCalculator, Num With ability to declare global properties on scope of running application by providing properties file in class path. Or by saving properties file with saveGlobalProperties()
It's possible to define default configuration with jcalc.properties file in root of classpath.
Example of jcalc.properties file where all properties are optional:

   roundingMode=HALF_UP
   scale=2
   stripTrailingZeros=true
   decimalSeparator.out='.'
   decimalSeparator.in='.'
   numconverter[0]=org.jdice.calc.test.NumTest$CustomObject > org.jdice.calc.test.NumTest$CustomObjectNumConverter
   operator[0]=org.jdice.calc.test.CustomOperatorFunctionTest$QuestionOperator
   function[0]=org.jdice.calc.test.CustomOperatorFunctionTest$SumFunction
