similar to: Rails 3 and saving decimal values from a form

Hi, It appears to me that the command: ruby script/generate scaffold whatever money_field:decimal(10,2) will not generate a valid migration. Therefore it appears to me only two ways to achieve the desired result is: 1.1 Omit the the precision/scale on the scaffold command 1.2 Edit the migration file by following the "do |t| ... end" with the command: change_column :whatever

Hi, What do you guys use to definitely handle decimal numbers? This is getting me crazy!

Hi All, I just created a new CRUD "expense" (using Rails 2.3.5 scaffold) which included "amount:decimal". When I: 1. populated the amount field of a new expense with 5 characters: 12.50 and 2. saved the new record I got a display of the new record that showed Amount to be merely "12". I clicked Update and put my cursor over the data field for Amount and got a

Hello folks, I´m here trying to find the way to solve my problem. When i try to run rake db:create or rake db:create:all the process stops and the databases are not created.

Hi: When debugging some floating point assembly, we found it is inconvenient to read the decimal constants in assembly. In hex form many FP numbers are immediately recognizable, their exponents are more obvious etc. We normally use hex form in debugger or LLVM IR, not sure what is the reason that we want to use decimal in assembly? The form change won't change precision or affecting

Rails3.1.3 I have db type, startp:integer I need to change it to float. More specifically, 1.2, 45.1, 143.8 ... I have two questions: 1. Is removing and adding the field through migration the only way? in other words, is there a single command to change the type? 2. Is there anyway to limit the decimal place to only one? 56.3, 34.2... are acceptable, but 23.112, 77.34, ... are

A small number of columns in the data I need to work with are strings, the rest numbers. I'm using read_excel() from the readxl package to get the data ; right after it, the string columns are of type chr and the rest num. I'm tasked with finding out which columns are integers. From an advice, I tried saving the spreadsheet content into a CSV then loading that, which works like a charm ;

Hi, I would like to store some text and decimal values in the following form: name dec.val dec.val ... dec.val name dec.val dec.val ... dec.val ... name dec. val dec.val ... dec.val To do so, I created a matrix of the necessary size (x row per y cols) with the command matrixname <- matrix(0,x,y) and proceeded to fill in the matrix with information drawn from a data frame. The

Hello, What is the easiest way which enables usage of decimal comma "," instead of decimal point (".") .

Hi, I have a mysql schema with some decimal(20,20) fields. Now, I made a rake db_schema_dump for deployment of my applications on other machines. Rails created a schema.rb with the decimal fields as float. After a rake db_schema_import the fields are just float not decimal. How can I force rails to create decimal(20,20) columns instead of float? Thx. Marc -- Posted via

Can someone please tell me the best approach to adding support for editing MySQL decimal types in rails?

Is there any way of doing this in llvm? Thanks and Regards -- -- Aparna Kotha Graduate Student Electrical and Computer Engineering

Hi, I came across the strangest issue I have no idea how it happened. In my development environment, I created a new migration and model that uses a couple of decimal column types (among others). Everything works great with sqlite and the development environment, business as usual. However, I deployed to production and for some completely unknown reason, this particular table (only this one)

Hi there, I want to figure out how to plot means, with 2 decimal places, of any Y variable on a scatterplot according to any X variable (which obviously should have limited scope). I already figured out how to plot the means, but without limiting their precision to 2 decimal places. This is the code I used once I had the scatterplot drawn: text(c(1990, 1992, 1994, 1996, 1998, 1999, 2000,
