## Converting Big to long long

Hey everyone, really cool stuff you are doing here. I am sorry if this is a very 'noob' question and I'm sure I am doing something wrong but I am programming a simple C++ calculator and would like to be able to use the pow function, but it gives me an error because pow doesn't support ttmath, so I would like to convert it to long long so that pow can work with it. Many thanks, Lachlan

Code:

#include <iostream>

#include <cstdlib>

#include <math.h>

#include </Users/craigmacphee/Downloads/ttmath-0.9.3/ttmath/ttmath.h>

using namespace std;

ttmath::Big<1,2> firstNumber = 1;

ttmath::Big<1,2> secondNumber = 1;

int operation = 1;

int main()

{

cout << "Addition = 1" << endl;

cout << "Subtraction = 2" << endl;

cout << "Multiplication = 3" << endl;

cout << "Division = 4" << endl;

cout << "Squared = 5" << endl;

cout << "Square Root = 6" << endl;

cout << "Power = 7" << endl;

cout << "What operation would you like to use? "; cin >> operation;

if(operation == 1)

{

cout << "Input your first number: "; cin >> firstNumber;

cout << "Input your second number: "; cin >> secondNumber;

cout << "The answer is " << firstNumber + secondNumber << endl;

}

if(operation == 2)

{

cout << "Input your first number: "; cin >> firstNumber;

cout << "Input your second number: "; cin >> secondNumber;

cout << "The answer is " << firstNumber - secondNumber << endl;

}

if(operation == 3)

{

cout << "Input your first number: "; cin >> firstNumber;

cout << "Input your second number: "; cin >> secondNumber;

cout << "The answer is " << firstNumber * secondNumber << endl;

}

if(operation == 4)

{

cout << "Input your first number: "; cin >> firstNumber;

cout << "Input your second number: "; cin >> secondNumber;

cout << "The answer is " << firstNumber / secondNumber << endl;

}

if(operation == 5)

{

cout << "Input your number to be squared: "; cin >> firstNumber;

cout << "The answer is " << firstNumber * firstNumber << endl;

}

// ERROR LIES IN FOLLOWING TWO IF STATEMENTS

if(operation == 6)

{

cout << "Input your number to be square rooted: "; cin >> firstNumber;

Big::ToDouble(double & out)

double firstNumber;

ttresult.ToDouble(firstNumber)

cout << "The answer is " << pow(firstNumber, secondNumber) << endl;

}

if(operation == 7)

{

cout << "Input your first number: "; cin >> firstNumber;

cout << "Input your second number: "; cin >> secondNumber;

cout << "The answer is " << pow(firstNumber, secondNumber) << endl;

}

}

if(operation == 6) { cout << "Input your number to be square rooted: "; cin >> firstNumber; ttmath::ErrorCode err; ttmath::Big<1,2> two = 2; ttmath::Big<1,2> result = ttmath::Root(firstNumber, two, &err); if( err == ttmath::err_ok ) cout << "The answer is " << result << endl; else cout << "incorrect argument or overflow" << endl; } if(operation == 7) { cout << "Input your first number: "; cin >> firstNumber; cout << "Input your second number: "; cin >> secondNumber; int carry = firstNumber.Pow(secondNumber); if( carry == 0 ) cout << "The answer is " << firstNumber << endl; else cout << "incorrect argument or overflow" << endl; }
