There is a similar question in here. Sometimes that solution gives exceptions because the numbers might be to large.

I think that if there is a way of looking at the bytes of a decimal number it will be more efficient. For example a decimal number has to be represented by some n number of bytes. For example an Int32 is represented by 32 bits and all the numbers that start with the bit of 1 are negative. Maybe there is some kind of similar relationship with decimal numbers. How could you look at the bytes of a decimal number? or the bytes of an integer number?

    If you are really talking about decimal numbers (as opposed to floating-point numbers), then Decimal.GetBits will let you look at the individual bits of a decimal. The MSDN page also contains a description of the meaning of the bits.

    On the other hand, if you just want to check whether a number has a fractional part or not, doing a simple

    var hasFractionalPart = (myValue - Math.Round(myValue) != 0)

    is much easier than decoding the binary structure. This should work for decimals as well as classic floating-point data types such as float or double. In the latter case, due to floating-point rounding error, it might make sense to check for Math.Abs(myValue - Math.Round(myValue)) < someThreshold instead of comparing to 0.
