Shell Programming and Scripting

How can I compare two decimal values within a function using Bash? Function fun2 isn't comparing the decimal values. Is there a way to do this using Bash or Korn?


#!/bin/bash
set -x


x=1
z=110



function fun1() { i=`bc << EOF 2>> /dev/null
scale=3
$x/$z
EOF`
echo $i >> /dev/null

p=`bc << EOF 2>> /dev/null
100 * $i
EOF`

s=`echo "$p" | cut -c1-3`
echo "$s%"
}


function fun2() { i=`bc << EOF 2>> /dev/null
scale=3
$x/$z
EOF`
echo $i >> /dev/null;

p=`bc << EOF 2>> /dev/null
100 * $i
EOF`

s=`echo "$p" | cut -c1-4`

if [ $s -lt "1.00" ]
then
echo "The value is less than 1.00%"
else
echo "$s%"
fi

}




if [ $x -eq $z ]
then
fun1
else
fun2
fi
