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).

thanks it helps me somewhat

For specific information see http://en.wikipedia.org/wiki/IEEE_754-2008#Formats, about the IEEE standard on floating point numbers.

The symbols you have encountered, -1.#IND00000000 and -1.#QNAN0, are commonly known as "not a number" (NaN) and "indeterminate" (IND). These symbols are typically displayed when there is an error or unexpected result in a mathematical calculation. NaN is used to represent a value that is not a valid number, while IND is used to represent a value that cannot be determined due to an error in the calculation process. In your C program, these symbols may appear due to division by zero, taking the square root of a negative number, or other mathematical errors. It is important to identify and address these symbols in your code to ensure accurate and reliable results.
