Math Question

OK I need to know the difference between two numbers. This is easy when I need to know the difference by subtracting the smaller number from the larger number however there are many cases where I need to know the difference of the numbers when I need to subtract the smaller number from the larger number. What would be the simplest way to convert a number that ends up being negative to a positive number. Example: the difference is -26 so I want it to be converted to 26.

I will have to run an if statement to check if its negative and run the operation, I assume, unless there is an easier way.

 

I think I got it.

I just checked if the value was less than zero then if it was set it to negative value so example:


diff = -diff

that seemed to work.

Hi Sir

Did you try uint ??

The unsigned integer type is uint. It takes 4 bytes of memory and allows expressing integers from 0 to 4 294 967 295.


or write a little method, something like :

int MathUnsignedInt(int value)
  {

   if(value<0)
     {
      return value * -1;
     }
   return value;
  }

MathAbs()

MathAbs()

I saw the MathAbs() function but wasn't sure what it actually did. The description seemed a bit cryptic to me. This will make a negative number a positive number?
