Re: [Pharo-project] Rounding float question again

by Nicolas Cellier

Hi Denis, If you decompose the operation performed by round: (146.015 / 0.01) rounded * 0.01 '146.015' asFloat is inexact '0.01' asFloat is inexact / 0.01 operation is inexact '0.01' asFloat is inexact (again) * 0.01 operation is inexact That means cumulating 5 inexact operations, how do you say "jouer Ã la roulette russe"? Pharo guys did propose a better scheme (146.015 * 100.0) rounded / 100.0 Since '100.0' asFloat is exact, that leave only 2 inexact operations and works much better (and we know the last one rounds exactly). But if (146.015 asFraction < 146.015s3) then you still have a problem with inexactness of original value. I see two solutions for this root problem: - don't use Float, but Fraction or ScaledDecimals - use a trick, asMinimalDecimalFraction which I proposed in http://code.google.com/p/pharo/issues/detail?id=4957 that will convert ('146.015' asFloat) to the exact fraction that is printed 146015/1000... (x asMinimalDecimalFraction roundTo: 1/100) asFloat would thus be close to your requirements...

[Pharo-project] Rounding float question again

by Denis Kudriashov

Hello. I know there are many similar questions. Maybe somebody give me fast answer. 146.015 roundTo: 0.01 => 146.01 I guess internal representation of 146.015 is something like 146.014999999999... That's why rounding result is 146.01 But how I can round arbitrary float my math root? How to fix my example to get 146.02? Best regards, Denis

Re: [Pharo-project] integration/review process

That would be much much better than what we currently have with mix of code agnostic google issue tracker + ST only MC repository... Another plus is also to make code visible/searchable/indexable outside our community, be it with less specialized (not so less powerfull) IDE.

Runs on 1.4 and 2.0 as long as you manually backport the newest filesystem packages (I've got both images on my machine and it works fine).

Hi! In Pharo, when an object is created, the #initialize message is sent to it automatically. You can create an #initialize method in your class and put whatever you want in it :). BTW, I copy this question to the pharo_users mailing list, since it looks a more appropiate place for it.
