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.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
