It's just a different printOn: method. The new one shows the "truth".
You must now use one of the print formatting methods to display
pretty Floats.

Every two different Float shall have a different printString:
(12.45) = (1245*0.01) -> false.So...The printString shall be the shortest decimal that rounds to the same float.
It's hard to demonstrate with a simple snippet, but you can check that we are very close yet:((Fraction readFrom: '12.450000000000001') - (1245*0.01) asTrueFraction) / (1245*0.01) ulp.
((Fraction readFrom: '12.45') - (1245*0.01) asTrueFraction) / (1245*0.01) ulp.
