Check if number is double or int

[HaLo2FrEeEk]

I need to check if a given number is an int or a double. I don't want to round doubles to ints, I just want to know if the number is an int or a double. Is there any way to do this?

For the record, I start with an 2 ints, one is the width of an image and the other a number I'll be dividing the width by. I need to be able to find out if the width is divisible by the number I'm dividing it by evenly, otherwise I need to alert the client.

Someone please help me.

The modulus operator gives you the remainder of one number divided by another number. The operator is %.

So...

            Console.WriteLine(5 % 3);
            Console.WriteLine(10 % 3);
            Console.WriteLine(27 % 10);
            Console.WriteLine(15 % 3);
            Console.WriteLine(12 % 4);

Outputs...
7
1
7
0
0


So when the modulus is zero, the numbers are evenly divisible and there is no fractional part.

I feel SO dumb. I just (literally, JUST) used MOD in php, I had an issue with a playlist in windows media player where I suddenly had a duplicate of every song, so I used mod to determine if the row number was even or odd and only pulled out the odd rows to remove the duplicates. I should have remembered this.

Thank you, very much.
