Re: [Pharo-users] Disabling Fractions ?

by Hernan Wilkinson

you should do that... one thing is how your model works and another is how it shows the results to a human (display, printer, etc)... so if you have a number renderer or something like that, you do asFloat there... but that is not enough, you will have to decide how many decimals you want to show, etc. so it is better to use #printShowingDecimalPlaces: and problem solved :-) On Sat, Jul 31, 2010 at 4:54 PM, Stanislav Paskalev <kshorg(a)gmail.com>wrote: > Purely for display.

Hi ben on which version should I load it? It is important that recentMessages works without shout.

Grrrr I know you were going to bother with that ;) I couldn't scape jahahaha ok...here it is: http://book.pharo-project.org/book/FAQ/ BUT I HATE MY STYLE. I cannot put a nice CSS or display of the page. If someone can help me, please....it is ugly. In addition, I didn't add it to http://www.pharo-project.org/documentation/faq because I think they are different kinds of FAQ. what do you think? I still hope someone has time to migrate the techincal stufff from SCG to the new book.

Re: [Pharo-users] Disabling Fractions ?

by Stanislav Paskalev

Purely for display. I'm doing a very basic accounting app that does not need full accuracy, but saying that the client should pay (X/Y) amount of cash .. that will be a problem :) In the end, I might as well keep fractions for the model itself, and just add asFloat on the view wherever required.

I do not like to manipulate float when I can have exact math operations. So I put asFloat exactly when I know I want to leave the math world to end up in the computer science world. Why do you need float and not fraction? You crunch matrix resolution with large numbers? Stef
