But did you try Klashxx's solution with backquotes?
Code:
#!/bin/sh

a=$1
b=`echo "$a * 0.43"|bc`
echo $b

... could utilize awk, which natively handles floats:
Code:
b=`echo $1|awk '{print $0*.43}'`

... my bad, missed the second page where this had been resolved ...

Thanks Jethrow, ur suggestion works Smilie

Code:
#!/bin/sh

a=$1
c=$2
##b=`printf "%.2f"  $1*0.43`
b=`echo $1|awk '{print $0*.43}'`
##b=`echo "$a * $c"|bc`
echo $b
