cant say it makes sense for me , why it assumes I want to +0.01 when I give 0.5 to 0.01 when it should assume I want to -0.01 ? is there a scenario that would not be true ?

take it this way: in C you��ll need to write:

for (int i = 0.50; i >= 0.1; i-=0.01) ��

which is also explicit about the decreasing ��i�� so I don��t understand why it does not makes sense for you :)

in any case its better than reversedo , thank you

this is correct behaviour (since 0.50 + 0.01 will be bigger than 0.01),
correct way to define this step is:

(0.50 to: 0.01 by: -0.01) do:[ :each| tp := tp + each ].

(by: -0.01), negative

hey guys I try to do a reverse interval like this

tp := 0.0.
(0.50 to: 0.01 by: 0.01) do:[ :each| tp := tp + each ].
tp inspect.

and I get nothing , is this a bug or a feature ?

i see a reverse method but looks weird to go that way and not very smalltalky / pharoic
