/BigInt-Calculator

A simple project in C to create a basic calculator that is capable of adding very big integers (that can't be stored in any data type)

Primary LanguageC

Implementation of Basic Arithmetic Operations for very big integers represented as a string

To build

make

To run

./bigCalc

Sample I/O

$ ./bigCalc 
Calc> 9999999999999524635735*52985256955318
529852569553154812702271599121088730
Calc> 2456574627537577357542662426462-23564626246464373575373
2456574603972951111078288851089
Calc> 1111111111111111+246363727
1111111357474838
Calc> 253252986498628/-7942970
-31883915
Calc> Exit
$

Notes

  • Type Exit to exit the calculator.
  • The input should be of form operand1 <op> operand2.
  • The operands can have any sign. (+/-).
  • Can handle integers as big as MAX_INT_LENGTH digits (can be modified in bigInteger.c).
  • Addition, subtraction and multiplication are done like regular methods.
  • Division is implemented as exponential subtraction (more like how long division works actually) and returns the quotient.
