I use the Printf package for that.

v := 65.456.

'With 2 decimal digits: %5.2f, or 3 like this: %6.3f'��

printf: {v. v}.

With 2 decimal digits: 65.45, or 3 like this: 65.456

It is in��http://www.smalltalkhub.com/#!/~philippeback/HOExtras

Printf

I am just used to C printf and well, I like the way it works.

Hi

I'm wondering if we do not have a bug here

12.222222222222221 roundTo: 0.1
��"12.200000000000001"

12.222222222222221 roundTo: 0.01
��"12.22"
