Euh, sure this works:

 (Number readFrom: 'FF' base: 16) printStringBase: 2

Number class>>#readFrom:base:
Integer class>>#readFrom:base:

So something like this should work:

(Integer readFrom: 'FF' base: 16) printStringBase: 2

Integer readFrom: 'FF' will not work since #readFrom: expects a string in decimal representation
and 'FF' is hexadecimal. It also wont work for large numbers due to sending it to "Integer".

Just use

(Number readFrom: '16rFF') printStringBase: 2

which works for large numbers

(Number readFrom: '16rFFFFFFFFF') printStringBase: 2
