similar to: Disappearing decimals... please help!

Another newbie question: How do i convert a float to a string, rounded to a certain number of decimals? Thanks -- Posted via http://www.ruby-forum.com/.

Hello, What is the easiest way which enables usage of decimal comma "," instead of decimal point (".") . I would like to force all RoR views to display float numbers with comma instead of decimal point and also to allow insertion of float numbers with comma in forms. Thanks in advance, Karel -- Posted via http://www.ruby-forum.com/.

We are running samba 2.0.4b to provide corporate print services. Everything with regards to printing is working like a charm. However, twice in the past two weeks, some of our Samba servers have disappeared from the WINS servers. The WINS servers are NT servers running 4.0SP5. The strangest part was that in one occurrence, it was the lone samba server at one location, but in the other

Back in 2.1.1 everything was sweet: Loading development environment (Rails 2.3.3) >> include ActionView::Helpers::NumberHelper => Object >> number_to_currency(12.3) >> "$12.30" Then I upgraded to 2.3.2 and: Loading development environment (Rails 2.3.3) >> include ActionView::Helpers::NumberHelper => Object >> number_to_currency(12.3) >> 12.3

Hi all, Apologies in advance if I got this one wrong, I''m still just a newbie ;-) Going through the Apple ADC RoR tutorial it suddenly occurred to me that the ''number_to_currency()'' helper method was not DRY streamlined. Scenario:: The "number_to_currency()" methods options hash works great when I need to dynamically display different currencies when I

I work in the UK and therefore most of my currency figures will be in UK pounds. I realise that to format a number to a currency format I can use: number_to_currency(amt, :unit => "?") but it would be more convenient to set ? as the default currency symbol. What is the best way to do that? Should I edit line 39 of this file:

Any ideas why I would get an error in a RJS helper on view helpers such as number_to_currency. Example: # my_template.rjs page.help_me # my_helper for my_controller def help_me number_to_currency(10) end I have also tired page.number_to_currency but that doesn''t work either. Cheers, Nicholas

Hi Gurus, I have a class, specified in models cart.rb, which doesn''t inherit from anything--it''s just a container class Cart ... I just discovered I can''t call number_to_currency in that class. Any idea how to "include" it in my code? I tried ActionView.number_to_currency without luck. I could kill a few lines of non-DRY regexp code in cart.rb if I could

I was wondering if this is possible. I have a model (Item) that contains products. These products have prices that I''d like to format using number_to_currency. Rather than doing this several times inside the view, I thought it might be nice to do it once inside the model. The item table has an field called regular_price which holds a currency amount. I would like to do something

I am using the number to currency function because i live in the uk and the company want me to only show values of the pound of course.I have created all my application using ruby script/generate scaffold_resource.... I have come across with a problem... this code is in my applcation: def number_to_currency(number, options = {}) options = options.stringify_keys precision, unit, separator,

so I am trying to sum month over month the amount that a user has posted. So for example: User 1: Jan $3000 Feb $4000 March $1500, etc. I can get this to work if I sum totals (aggregate of all users) but just not by user. Here is my code in the controller: def index @users = User.find :all, :order => ''name ASC'' @deal_groups = Deal.find(:all).group_by {|t|

I was trying to write a wrapper for number_to_currency to return currency in pounds. I used a helper class to do this. def number_to_pounds(amt) number_to_currency(amt, :unit => "£") end This works fine, but I am trying to understand why I can''t use a symbol to pass the values. I thought symbols were like pointers. (you now know I am a newbie). def

I think I must be missing something obvious, but I'm having trouble getting a data transformation to work on groupings of data within a data frame (csss3) as defined by 2 factors (population, locid). The data are sorted by year within locid within population and I want to lag another variable (dbc), i.e, shift them down by 1 row replacing the first row with NA, within groups defined by

I know, I know, they''re not allowed to. But here''s my problem. I''ve got a really simple model with two fields, name and price, which I want to show in a form select drop-down. "collection_select" takes a ''text_method'' parameter, which is the method in the model that gets its value placed in the <option> tag. Because I want to show both

Just noticed that I get a similar error about object 'kronecker' in "Matrix" package when trying to load "lme4". So this is a more pervasive problem. Brian Brian S. Cade, PhD U. S.

I am trying to implement an ANOVA on a pair of quantile regression models in R. The anova.rq() function performs a basic check to see whether the models are nested, but I think this check is failing in my case. I think my models are nested despite the anova.rqlist() function saying otherwise. Here is an example where the GLM ANOVA regards the models as nested, but the quantile regression ANOVA

I wish to create a matrix of all possible percentages with two decimal place percision. I then want each row to sum to 100%. I started with the code below with the intent to then subset the data based on the row sum. This works great for 2 or 3 columns, but if I try 4 or more columns the number of rows become to large. I would like to find a way to break it down into some kind of for loop, so
