Ok for the advice
Now round: aNumberOfDigits seems to work fine.

No it's not, but issues are timing out too fast ;) https://pharo.fogbugz.com/f/cases/15471/Can-t-round-Float-fmax-to-2-decimal-... https://pharo.fogbugz.com/f/cases/15472/Fraction-rounding-to-n-decimal-place... https://pharo.fogbugz.com/f/cases/15473/Float-round-to-n-decimal-places-is-n... I hate to say that, but try in python, they got it right...

Unless you're dealing with fixed precision* entities, it's usually better to specify digits to display in printing methods themselves (#printShowingDecimalPlaces: & friends in base image). As per previous discussions around this that arise every second year or so, rounding the number itself (as long as we're dealing with floats) will never work as you want reliably.

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

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