Floating point comparison in shell

Question

Can you please suggest to me the syntax for doing floating point comparison in a Bash script? I would ideally like to use it as part of an if statement. Here is

Answer 1

bash doesn't do floats, use awk

key1=12.3
result=12.5
var=$(awk 'BEGIN{ print "'$key1'"<"'$result'" }')    
# or var=$(awk -v key=$key1 -v result=$result 'BEGIN{print result

there are other shells that can do floats, like zsh or ksh, you might like to try using them as well
