The two problems were identified from the beginning: 1) 2.e5 and .2 did work in old squeak images, but no more with SqNumberParser Rationale: SqNumberParser is for parsing number literals in squeak syntax, and those extensions are not identified squeak syntax
If you need these syntax, the best thing is to subclass the NumberParser. For example, I must have a FORTRANNumberParser available somewhere... 2) Silently returning zero in case of error. This was one of the goal of SqNumberParser: let programmer choose the appropriate behaviour - raise an Exception - answer nil - answer a default value (zero) The last solution has been connected to Number class>>#readFrom: for historical compatibility reasons. I agree this conservative choice was unfortunate. Pharo should not fear and break compatibility on such dumb behaviours.
