I am working with devcpp, and have written a c program

I am working with devcpp, and have written a c program. After I had compiled it and make it to run, I got these symbols at some places (i.e for some values of input) . I want to know what are they and what do they represent.

symbols:
-1.#IND00000000
-1.#QNAN0

symbols:
-1.#IND00000000
-1.#QNAN0

The QNAN0 is short for "Not a Number": it represents that the floating point number is not a valid one. This could be because of overflow (number too big) or underflow (number too small).

Not sure about the other one (its been a while since I've seen that error).
