You get 'floating point error' when you divide by zero, check to see if things are getting parsed the way you expect.
You do not need to use fgetc to read in text data! Try scanf. Or better yet, sscanf. Read in data one line at a time then feed it through scanf to get what you want in one go.
You'll get purists complaining about scanf and its dangers but its far preferable to building your own integer-parsing routines. Used in this fashion it is fairly safe, with no risk of buffer overflows and none of the strange half-a-line-eaten problems plain scanf is infamous for.

Reason: adding more code
Does anyone have a simple way of doing floating point ("fp") division? For example, if I divide 3 by 5, I can get 0.6. The built-in calc (`bc`) will perform fp multiplication, but not division, at least not straight-up (i.e., starting bc and just typing in 3/5).

Hi,
Could any one tell me how to compare to floating point no. using test command. As -eq option works on only intergers.

if
then
echo "equal"
else
echo "not equal"
