BASH question




I thought this was simple, but I've not yet been able to figure out what is wrong.

#!/bin/sh

PERMINUTE=$((28.95/432000))
echo "$PERMINUTE"


What I'm looking for is $PERMINUTE to be the value of 28.95/43200.

I thought I had the syntax correct, but when I execute it I get:

./calc2.sh: line 3: 28.95/432000: syntax error in expression (error token is ".95/432000")

Any ideas?

Thanks,
Mike
