What is -1#IND in c++. I'm using double/ float data type to store skewness of some data samples. There I am getting -1#IND for some of skew values, because of that classifier is giving me wrong results...

I explained in the answer http://tech.queryhome.com/46882/what-is-1%23ind-in-c?show=46954#a46954

Can you be specific about what is not clear.

If you get some strange non-numeric output where you're expecting a number, you've either exceeded the finite limits of floating point arithmetic or you've asked for some result that is undefined.

Now coming to your question -
If your operation would generate a larger positive number than could be stored in a double, the operation will return 1.#INF on Windows or inf on Linux. Similarly your code will return -1.#INF or -inf if the result would be a negative number too large to store in a double.

Let me know if this clarifies your doubt.
