Hi all, I'm having a look how floats are printed. Why we check two times if a Float is infinite ? A first time in: Float>>printOn: stream base: base ... self isInfinite ifTrue: [ stream nextPutAll: 'Float infinity'. ^ self sign = -1 ifTrue: [ stream nextPutAll: ' negated' ] ]. ... and a second time in: Float>>absPrintExactlyOn: aStream base: base ... self isInfinite ifTrue: [ aStream nextPutAll: 'Float infinity'. ^ self]. ... the same in Float>>absPrintInexactlyOn: aStream base: base ... self isInfinite ifTrue: [aStream nextPutAll: 'Float infinity'. ^ self]. ... Apparently the last two methods are never called when number is infinite. I remove the second checks and apparently nothing breaks (all number tests are still green).
