-[![Build Status](https://travis-ci.org/varocarbas/FlexibleParser_Java.svg?branch=master)](https://travis-ci.org/varocarbas/FlexibleParser_Java)
+[Test program](https://github.com/varocarbas/FlexibleParser_Java/blob/master/all_code/Test/src/Parts/NumberParser.java)
 
-**NOTE:** this is the conversion to Java of the original C# code stored in the [FlexibleParser repository](https://github.com/varocarbas/FlexibleParser).

-FlexibleParser is a multi-purpose parsing library based upon the following ideas:
+## Introduction
 
-- Intuitive, adaptable and easy to use.
-- Pragmatic, but aiming for the maximum accuracy and correctness.
-- Overall compatible and easily automatable. 
-- Formed by independent JARs managing specific situations.
+The ```NumberParser``` package provides a common framework to deal with all the Java numeric types. It relies on the following four classes (NumberX):
+- ```Number``` only supports the ```double``` type.
+- ```NumberD``` can support any numeric type via ```Object```. 
+- ```NumberO``` can support different numeric types simultaneously. 
+- ```NumberP``` can parse numbers from strings. 
 
-## Parts
+```Java
+//1.23 (double).
+Number number = new Number(1.23); 
 
-At the moment, FlexibleParser is formed by the following independent parts:
+//123 (int).
+NumberD numberD = new NumberD(123);

-It allows to easily deal with a wide variety of situations involving units of measurement.
-Among its most salient features are: user-defined exception triggering and gracefully managing numeric values of any size.

' (char).
+NumberO numberO = new NumberO
+(
+	1.23, new ArrayList() 
+	{{ 
+		add(NumericTypes.Integer); 
+		add(NumericTypes.Character); 
+	}}
+);

+NumberP numberP = new NumberP
+(
+	"1.23", new ParseConfig(NumericTypes.Long)
+);

+## Common Features
+
+All the NumberX classes have various characteristics in common.
+- Defined according to ```getValue()``` (```double``` or ```Object```) and ```getBaseTenExponent()``` (```int```). All of them support ranges beyond [-1, 1] * 10^2147483647. 
+- Static (```NumberD.Addition(numberD1, numberD2)```) and non-static (```numberD1.greaterThan(numberD2)```) support for the main arithmetic and comparison operations.
+- Errors managed internally and no exceptions thrown.
+- Numerous instantiating alternatives.
+
+```Java
+//12.3*10^456 (double).
+Number number = new Number(12.3, 456); 
+
+//123 (int).
+NumberD numberD = 
+(
+	new NumberD(123).lessThan(new NumberD(new Number(456))) ?
+	//123 (int)
+	new NumberD(123.456, NumericTypes.Integer) :
+	//123.456 (double)
+	new NumberD(123.456)
+);
+
+
+//Error (ErrorTypesNumber.InvalidOperation) provoked when dividing by zero.
+NumberO numberO = NumberO.Division
+(
+	new NumberO
+	(
+		123.0, OtherTypes.IntegerTypes
+	)
+	, new NumberO(0)
+);
+
+//1.234000000000e+308*10^5373 (double).
+NumberP numberP = new NumberP("1234e5678");
+```
+
+## Math2 Class
+
+This class includes all the NumberParser mathematical functionalities.
+
+### Custom Functionalities
 
+- ```RoundExact```/```TruncateExact``` can deal with multiple rounding/truncating scenarios not supported by the native methods.
+- ```GetPolynomialFit```/```ApplyPolynomialFit``` allow to deal with second degree polynomial fits. 
+- ```Factorial``` calculates the factorial of any integer number up to 100000. 
+
+```Java
+//123000 (double).
+Number number = Math2.RoundExact
+(
+	new Number(123456.789), 3, RoundType.AlwaysToZero, 
+	RoundSeparator.BeforeDecimalSeparator
+);
+
+//30 (double).
+NumberD numberD = Math2.ApplyPolynomialFit
+(
+	Math2.GetPolynomialFit
+	(
+		new NumberD[] 
+		{ 
+			new NumberD(1), new NumberD(2), new NumberD(4) 
+		}, 
+		new NumberD[] 
+		{ 
+			new NumberD(10), new NumberD(20), new NumberD(40) 
+		}
+	)
+	, new NumberD(3)
+);
+
+//3628800 (int).
+NumberD numberD = Math2.Factorial(new NumberD(10));
+```
+
+### Native Methods
+```Math2``` also includes ```NumberD```-adapted versions of a big number of ```Math``` and .NET ```System.Math``` methods. 
+
+It also includes ```PowDecimal```\\```SqrtDecimal``` which allow to unrestrictedly use NumberX variables with ```Math.pow```\\```Math.sqrt```. Note that this Java version doesn't rely on the original C# custom implementation (detailed explanations in [varocarbas.com Project 10](https://varocarbas.com/fractional_exponentiation/)) because of only making sense within the .NET conditions (i.e., high-precision ```decimal``` type not natively supported by the in-built methods).
+
+```Java
+//1.582502898380e+14 (double).
+Number number = Math2.PowDecimal
+(
+	new Number(123.45), 6.789101112131415161718
+);
+
+//4.8158362157911885 (double).
+NumberD numberD = Math2.Log(new NumberD(123.45));
+```
