today, I have copied a simple script which runs correctly on a computer to another one. But, the latter informs me:
Floating point exception!
@ ./command_module a b c
where command_module is the module compiled by myself.
So, I have fixed it by following steps：
1. append the current directory of the command_module to PATH
2. delete the characters of ./
3. rename command_module as commandmodule, else the error is still informed.
So, my question is what is the reason for it? Although it seems that the script is running correctly again, I am confused... who knows why?

What is in that script?

What line causes that error?
What is the full error message?

None of the steps you describe would fix that error, unless having the additional directory in your PATH caused the script to call a different version of a command.
The error "BASH: floating point exception " are outputed at the lines of
case 2 and 3.
And AutoRandom, lp_solve, lpsolve, combine are executable files compiled by myself.
The full error message:
+ ./lp_solve -time -sp secure.lp
./ExpScriptOld: line 55: 7304 Floating point exception./lp_solve -time -sp secure.lp >$lpfilename 2>&1
What is '@'?
@ is typed by myself. Sorry, just means AT.
The script is pasted here:

I have the following code snippet in bash
if ]; then
minm=`echo "$diff" | bc`
fi
It works well for most of the cases. However lets say diff is -0.17 and minm is -0.0017. In such a case the comparison seems to fail. Is the correct way to compare a mixture of positive and... (12 Replies)
Hello,
I have often found bash to be difficult when it comes to floating point numbers. I have data with rows of tab delimited floating point numbers. I need to find the smallest number in each row that is not 0.0. Numbers can be negative and they do not come in any particular order for a given... (9 Replies)
Heyas
I have a script (vhs - video handler script, using ffmpeg) to encode videos.
It also encodes a dvd, but until now just non-copy-protected ones, so i've tried to add/implement a vobcopy wrapper to be used by my script.
At first it looked quite fine, but when changing from the first VOB... (9 Replies)

Dear all,
I have the following question. Let's say that I have the following script

value=0.4987865
a=` printf "%6.2f" $value `
b=`echo $value + $value | bc -l`
echo $a
echo $b
exit
And the exit is:
0,00

Thus, the problem is that the printf order does not... (2 Replies)
