hi all, i have the following problem using awk in a script
i want to read the values from a column with real numbers and calculate the mean.the problem is that when i use a statement such as this
num = $4
i cant find a way to convert the variable from string to floating point to perform... (7 Replies)
Hi,
Could any one tell me how to compare to floating point no. using test command. As -eq option works on only intergers.
i=5.4
if
then
echo "equal"
else
echo "not equal"
fi
here output will be equal even though no. are unequal.
Thanks,

Hi All,
I got this script that pulls the Amps value from our RPC's , I basiclly want to compare the valued with a "limit" value -- if the numbers match or are greater than the definded value ...do something. My problem is I cant seem to figure out how to compare floating points...
here is... (1 Reply)
Hi All,
I'm trying to extract some floating point numbers from within some HTML code like this:

Hi guys
I have problem with my simple calculator, author of my book wrote
One way I tried is to test if one the inpur number is grater than zero, and then substatct
And my protptype function is

I have started using bash but this script which I am working on it, is in c chell. So here is my simple problem:
set x = 0.4124\0.234
echo $x
0.4124.0.234
Same operation in Bash gives me correct result in my terminal. So there is something with my c shell that is causing this behaviour.... (8 Replies)
I have the following code snippet in bash
if ]; then
minm=`echo "$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)
