What does ^ operator do?

I thought that ^ did that. I expected:

10^0=1
10^1=10
10^2=100

What I'm getting

10^0=10
10^1=11
10^2=8

the actual code is

int value = 10 ^ exp;

repl开发者_Python百科acing exp for 0, 1, and 2 What does the ^ operator do?

Math.Pow(x, y) to get x raised to the power of y. You were doing an XOR. C# operators

You want to do:

Math.Pow(10, exp);

This actually produces a double though so you'll need to cast it down if you really want an int.

In c#, ^ is the logical XOR operator.

As others have said, you need you use Math.pow(x, y) to do x^y in C#. The ^ operator is actually a logical XOR operator on the bits of the two numbers. More information on the logical XOR can be found here: http://msdn.microsoft.com/en-us/library/zkacc7k1.aspx

Math.Power(10,exp) works like charm...

In C#, the ^ operator is the logical XOR operator.

^ is the XOR operator.

http://en.wikipedia.org/wiki/Xor

If you want to raise a number to a power, use

Math.Pow(num, exp);

There is no operator for this. Use Math.Pow.

There is a full list of all the C# operators with linked documentation on each one.

The thing is that ^ is equivalent for XOR, that's why 10 ^ 0 = 10 because

1010 XOR    1010 XOR
0000 =      0010 =
1010        1000

You need to use Math.Pow method.

P.S. = 10^2 actually returns 8...
