After the some calculations with float values, instead of showing something like: 123.4567890, wierd characters of: 1.#IND00000 were displayed......
What are the possible causes for this to happen? And what does it mean by 1.#IND00000???

What are the calculations you're doing? And did you actually try doing a simple google search? Because I did one and found this link:

If you understand what you're doing, you're not learning anything.
#INF - infinity (mostly because things have gotten really big)
#IND - indefinite (mostly because things have gotten really small)
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Yes that is it! It happened when I divide a value by zero. My question is: How to use if statement as a condition for #IND values?
i.e:
if (value != Indefinedvalues)
if the value is not a zero I can just:
if (value != 0)...
But how to do it for indefined values?
if (value != #IND) ?
How?

There may be something in either math.h or float.h (can't remember)
Something along the lines of isInf(), isNan() etc.

int isfinite(fpval)
int isinf(fpval)
int isnan(fpval)
int isnormal(fpval)
are all defined in <math.h>
