This function calculates the subtraction of two long <em> positive </em> integers stored as character strings, in the given numerical base. The maximum number of digits of either of the numbers is only limited by the amount of memory available.

Example 1

#include <codecogs/maths/arithmetic/subtract.h>
#include <iostream>
 
int main()
{
  std::string a("232342353"), b("73452344"),
  c = Maths::Arithmetic::subtract(a, b, 8);
  std::cout << "The following is a base 8 operation" << std::endl;
  std::cout << a << " - " << b << " = " << c << std::endl;
  return 0;
}
Output:
The following is a base 8 operation
232342353 - 73452344 = 136670007

Note

The first number needs to be greater than the second, otherwise the function will exit.
