Hello all!

I have som numbers coming from somewhere with some strange format, such as, 19.9899992.
Well, I really need this number with 2 decimals, 19.99.

How do I round this number using CSHELL???

Thx.

echo 'scale=2; 19.9899992 / 1' | bc

Thx for your help,but I have tryed this and it does not round the number to 19.99 and yes it just cut the number like 19.98!!!

Thx for your help.

if you have /usr/bin/printf:

printf "%.2f\n" 19.9899992

if you don't:

echo 19.9899992 | nawk '{printf("%.2f\n", $0)}'

Or if you don't have either printf or nawk but have perl, you could also use:

Code:

echo 19.9899992 | perl -e "$i = <>; printf \"%.2f\n\", $i"
