Converting a decimal into integer

idro · #1 (**permalink**) 10-29-2007

Hi all,

I'm trying to convert a decimal number into an integer number; I'm doing this:

n=`echo |awk '{ print "'"$mem"'"*10}'`

where the variable mem is equal to 3.7
I'd like to obtain 37, but the expression above gives me 30.

Help please!!!!
thx a lot

Try

Code:

n=`echo "$mem * 10" | bc`

It works, but now I obtain, 37.0.
I'd want 37.

Code:

echo '3.7 * 10' | bc | sed 's/[.].*//'

Code:

echo '3.7'  | nawk '{printf("%d\n", $1 * 10)}'
