IF statement on floating point variable in scientific format
Hi all,
I'm struggling Smilie to make a an if statement on two variables in scientific format.
e.g.
Code:
a=1.23e+01
b=3.21e+02

I know that it can be done with bc if the variable are not in scientific format.
But what to do in this case???
Thank you,

awk can understand numbers in scientific format.

So, what what are you actually trying to do? Compare them how?

I just would like to do something if one is greater than the other; something like

Code:
if(${a}>${b})
 echo 1
else
 echo 2

Code:
if awk -v A="1.23e+01" -v B="3.21e+02" 'BEGIN { if(A>B) exit 0;  exit 1 }'
then
        echo "A>B"
else
        echo "A<=B"
fi
