Multiplication issue with Visual Studio debugger for C #

If I enter 174 * 256 * 256 * 256 into the viewport in the C # debugger, the result will be -1375731712. I guess this has something to do with 256, but I would appreciate a little guidance.

Thank!!

Try entering this:

174 * 256 * 256 * 256f

therefore, the result will not be transmitted as an integer, but as a float.

No, it has nothing to do with 256. This is simply the result of this multiplication greater than the maximum possible signed 32-bit integer, so you got an overflow.

Try this instead:

174L * 256L * 256L * 256L

These are 64-bit integer literals.
