Thanks Andy, that resolved the error, but returns $PERMINUTE as 0. It should be something like .00067xxxxx. Is there a way to do that?

Farm it out to bc

echo "scale=10 ; 28.95 / 432000" | bc

Thanks again Andy. Is this what you mean?

#!/bin/sh

#PERMINUTE=$(( 29 / 432000 ))
PERMINUTE=$(echo "scale=10; (28.95 / 432000" | bc ))

echo "$PERMINUTE"

This gives me the following error:

./calc2.sh: line 4: syntax error near unexpected token `)'
./calc2.sh: line 4: `PERMINUTE=$(echo "scale=10; (28.95 / 432000" | bc ))'

I apparently am not following your meanings exactly.

Thanks,
Mike
