# BigNumber  [](https://github.com/Limeoats/BigNumber/blob/master/LICENSE.md) BigNumber is a C++ class that allows for the creation and computation of arbitrary-length integers. The maximum possible length of a BigNumber is `std::string::max_size`. ## Installation To add BigNumber to your C++ project, you can download the `bin` folder from this repository, which contains the library and include files. Then, simply include the header file in whichever file you need a BigNumber and link to the library file. `#include "bignumber.h"` ## Usage ### `BigNumber(string)` You can also use the `=` operator to set a BigNumber equal to an existing BigNumber, a number, or a string of numbers. Examples: BigNumber b("5"); //BigNumber b is created with value 5. BigNumber c("-20"); //BigNumber c is created with value -20. BigNumber d("0"); //BigNumber d is created with value 0. BigNumber e = b; //BigNumber e is created with value 5. BigNumber f = 30; //BigNumber f is created with value 30. BigNumber g = "2060"; //BigNumber g is created with value 2060. BigNumber h(22); //BigNumber h is created with value 22. ## Methods ### `add(BigNumber other)` Adds another BigNumber to the current instance `BigNumber("4").add(BigNumber("20")) => BigNumber("24")` ### `subtract(BigNumber other)` Subtracts another BigNumber from the current instance `BigNumber("30").subtract(BigNumber("45")) => BigNumber("-15")` ### `multiply(BigNumber other)` Multiplies the BigNumber by another BigNumber `BigNumber("12").multiply(BigNumber("4")) => BigNumber("48")` ### `divide(BigNumber other)` Divides the BigNumber by another BigNumber `BigNumber("30").divide(BigNumber("5")) => BigNumber("6")` ### `pow(int exponent)` Raises the BigNumber to the power of the exponent `BigNumber("2").pow(3) => BigNumber("8")` ### `getString()` Returns the BigNumber as an std::string `BigNumber("3824").getString() => "3824"` ### `setString(std::string newStr)` Sets the BigNumber's internal number string to a new string `BigNumber("2847").setString("38") => BigNumber("38")` ### `negate()` Changes the sign of the BigNumber BigNumber("3").negate() => BigNumber("-3") BigNumber("-27").negate() => BigNumber("27") ### `equals(BigNumber other)` Checks if the other BigNumber is equal to this one `BigNumber("24").equals(BigNumber("28")) => false` ### `digits()` Returns the number of digits in the BigNumber `BigNumber("28374").digits() => 5` ### `isNegative()` Determines whether a BigNumber is negative `BigNumber("-278").isNegative() => true` ### `isPositive()` Determines whether a BigNumber is positive `BigNumber("-3").isPositive() => false` ### `isEven()` Determines whether a BigNumber is even `BigNumber("28472310").isEven() => true` ### `isOdd()` Determines whether a BigNumber is odd `BigNumber("283427").isOdd() => true` ### `abs()` Gets the absolute value of the BigNumber `BigNumber("-26").abs() => BigNumber("26")` ## Operator overloads The following operators have been overloaded to work with BigNumbers: ### `<<` Output stream operator `std::cout << BigNumber("26") << std::endl => 26` ### `+` Addition operator `BigNumber("2") + BigNumber("4") => BigNumber("6")` ### `-` Subtraction operator `BigNumber("0") - BigNumber("2000") => BigNumber("-2000")` ### `*` Multiplication operator `BigNumber("-20") * BigNumber("-5") => BigNumber("100")` ### `/` Division operator `BigNumber("10") / BigNumber("-2") => BigNumber("-5")` ### `==` Equal to operator `BigNumber("24") == BigNumber("24") => true` ### `>` Greater than operator `BigNumber("2") > BigNumber("6") => false` ### `<` Less than operator `BigNumber("2") < BigNumber("6") => true` ### `>=` Greater than or equal to operator `BigNumber("34") >= BigNumber("22") => true` ### `<=` Less than or equal to operator `BigNumber("383") <= BigNumber("383") => true` ### `=` Assignment operator `BigNumber c("3") = BigNumber("8") => BigNumber("8")` ### `+=` Adds and assigns to the BigNumber `BigNumber c("4") += BigNumber("3") => BigNumber("7")` ### `-=` Subtracts and assigns to the BigNumber `BigNumber c("28") -= BigNumber("3") => BigNumber("25")` ### `*=` Multiplies and assigns to the BigNumber `BigNumber c("3") *= BigNumber("4") => BigNumber("12")` ### `/=` Divides and assigns to the BigNumber `BigNumber c("30") /= BigNumber("30") => BigNumer("1")` ### `++ (Prefix)` Increments the BigNumber and returns the newly incremented number `++BigNumber("10") => BigNumber("11")` ### `-- (Prefix)` Decrements the BigNumber and returns the newly decremented number `--BigNumber("34") => BigNumber("33")` ### `++ (Postfix)` Increments the BigNumber but returns the original value `BigNumber("20")++ => BigNumber("20")` ### `-- (Postfix)` Decrements the BigNumber but returns the original value `BigNumber("14")-- => BigNumber("14")` ### `[]` Indexing operator `BigNumber d("26")[1] => 6` ## License This project is under the [Apache License](https://github.com/Limeoats/BigNumber/blob/master/LICENSE.md). ## Credit The BigNumber class was created by [Mark Guerra](http://www.twitter.com/Limeoats).
