The difference between the two numbers

Question

I need a perfect algorithm or C # function to calculate the difference (distance) between two decimal numbers.

For example, the difference between:
100 and 25 75
100 and -25 125
-100 and -115 15
-500 and 100,600

Is there a C # function or a very elegant algorithm to calculate this or do I need to go and handle each case separately with ifs.

If there is such a function or algorithm, which one?

Answer 1

You can do it like this:

public decimal FindDifference(decimal nr1, decimal nr2) { return Math.Abs(nr1 - nr2); } 

Answer 2

 result = Math.Abs(value1 - value2); 

Answer 3

Just add this since no one wrote it here:

While you can use

 Math.Abs(number1 - number2); 

which is the easiest solution (and accepted answer), I am surprised that no one wrote what Abs actually does. Here's a solution that works in Java, C, C # and any other language with syntax like C:

 int result = number1 - number2; if (result < 0) { result *= -1; } 

It is so simple. You can also write it like this:

 int result = number1 > number2 ? number1 - number2 : number2 - number1; 

The latter can be even faster if it is compiled (both have the same subtraction, but in the former case there is a multiplication in some cases, and the latter is not). The first one actually does the work of Abs.

Answer 4

I don't think this is possible in C #, you might have to take a look at its implementation in Assembler
