then
        echo "something"
fi

...but, as you discovered, shell does not support floating point. KSH is the only shell that does.

You can use awk instead, but this is expensive.

Code:
if awk -v VAR1="$VAR1" -v VAR2="$VAR2" 'END { if(!(VAR1<VAR2)) exit 1}' /dev/null
then
        echo "var1 < var2"
fi

thank you for the response!

the script i'm working on is pretty huge. but here is the part i just need to modify to be able to support a floating point:

Code:
if (( ${CURRENTSTE} == ${CSVCSTE} ) && ( ${LASTSTECHANGE} -ge ${CSVCSTEAGE} )) ; then

any one of these variables can have a floating point.

the script is written in bash.
