Rounding question

[Wrathchild]

Thanks to this board I was able to figure out how to us bc effectively and then drop off the excessive numbers since I want the format 000.00

My question is right now I'm just cutting off the numbers to the right of the 2nd decimal position, so the hundreths aren't alwasy correct due to lack of rounding. How can I incorporate rounding?

PERCENT=`printf "%s\n" "scale = 5; ($COUNT5 / $COUNT * 100)" | bc`
PERCENT=${PERCENT%???}

What about this ?
$COUNT5 / $COUNT * 100 [/!]+ 0.05[/!]

Hope This Helps, PH.

ok, what am I missing?
Syntax error:

PERCENT=`printf "%s\n" "scale = 5; ($COUNT5 / $COUNT * 100 [/!]+0.05[/!]) " | bc`

PERCENT=`printf "%s\n" "scale = 5; ($COUNT5 * 100 / $COUNT + 0.005) " | bc`

Sorry for the typo and the wrong TGML :~/
$COUNT5 / $COUNT * 100 [!]+ 0.005[/!]

no problem PHV, you're due one in a million postings

This doesn't seem to be rounding, unless I'm just not understanding what's going on:
17235/17303 = .99607 so I would like to see 99.61%

I meant this:
COUNT5=17235;COUNT=17303
PERCENT=`printf "%s\n" "scale=5; $COUNT5/$COUNT*100+0.005" | bc`
PERCENT=${PERCENT%???}
echo $PERCENT

nevermind...I applied it to the wrong line of code

Thanks guys, that did it. I wasn't sure if there was a "round" function or not.
