Hi guys,

In Pharo 2.0, the expression "Number readFrom: '2.5850009999999998e+04' " would answer��25850.01 , but in Pharo 3.0 it answers:��2.5850009999999997 ��which is a kind of WTF to me.

Checking the differences it seems in Pharo 2.0��ExtendedNumberParser (used from Number >> readFrom: ) ��implemented:

allowPlusSign

^true

However, in Pharo 3.0 it seems subclasses of��NumberParser have been merged directly in��NumberParser class (and so Number >> readFrom: uses this class now).��

But.. (and this is the difference), NumberParser implements:

allowPlusSign

^false

So I wonder...was this on purpose or a side effect? Why would we want to reject using + as part of the exponential notion??��

So in my case now I must do an override to:

NumberParser >> allowPlusSignInExponent

^ true

Thoughts?
