Hi Dieter, Sorry my mistake. I wanted to convert them into Decimal (not Hexadecimal). Given this string, the desired answer follows: > ascii_str <- "ORQ>IK" 79 82 81 62 73 75 > ascii_str2 <- "FDC" 70 68 67 - Gundala Viswanath Jakarta - Indonesia On Mon, Dec 22, 2008 at 5:49 PM, Dieter Menne <dieter.menne at menne-biomed.de> wrote: > Gundala

Try this: 0.7-0.3==0.4 (We get FALSE) 0.7-0.3<0.4 (We get TRUE) but 0.8-0.3==0.5 (TRUE) 0.8-0.3<0.5 (FALSE) Funny, he? There is a way around: round(0.7-0.3,1)==0.4 (TRUE) Obviously there is a problem with some combinations of decimal subtractions, that - we have the feeling - shouldt be solved.

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

Hi, I am sure there is a reason but ...... why larger decimal numbers get rounded to the nearest integer? Example: a <- 3308000.5 a [1] 3308001 I would like my numbers to be decimals .... since they do represent coordinates and i don't want them rounded .... how can i keep them as they are? Thanks, Monica _________________________________________________________________

Hi, Whenever I have a MySQL query that returns a Decimal result to R I get the following warning in R: Warning message: RS-DBI driver warning: (unrecognized MySQL field type 246 in column 1) I get this for a simple query like "SELECT 2, 2.5" !! I am using: R ver 2.1.1 RMySQL ver. 0.5-7 DBI ver. 0.1-10 MySQL Ver 14.12 Distrib 5.0.18. Please Help! Jason

Can someone please tell me the best approach to adding support for editing MySQL decimal types in rails? I have a field in the DB that represents currency, and the view will not let save anything past the decimal place so, 10.99 becomes 10.00 automatically. Any help is appreciated. -- Posted via http://www.ruby-forum.com/.

I''m having problems with using Rails for a financial application: the database stores financial fields as decimal, but ActiveRecord converts these to float - so I get the rounding errors you''d expect (http://www.mindprod.com/jgloss/floatingpoint.html). This has come up recently, and the recommended fix seems to be to be Tobi Luetke''s ''money'' gem

Hello, I am trying to do a spearman correlation. My data has tied values. To overcome this issue, I am adding some random noise (values) to my original data. However when I add the random noise to the data, the final matrix does not show the new values. I guess the reason being that the noise I add is very small and the full value including the decimals gets truncated to show only the value

Hi, Novice UsR here. I have a csv file that contains 13 columns of numeric data that have decimal places (for the most part). After reading in the file RevFCast = read.csv("RevAnalysisNov2016_April2018.csv", header=TRUE, dec = ".", stringsAsFactors=FALSE) and viewing the data View(RevFCast) Some of the fields came in with the correct decimals and some not? The view in R:

Hi everybody, I'm trying to set the number of decimals (i.e. the number of digits after the "."). I looked into options but I can only set the total number of digits, with options(digits=6). But since I have different variables with different order of magnitude, I would like that they're all displayed with the same number of decimals. I searched for it and found the format()

I am trying to use round()to force R to display a specific number of decimals, but it seems to display <=2 decimals no matter what I specify in the digits argument. As an alternative I tried signif(), but it also produces unexpected results. See example code and results below. Format() works, but then the result no longer is numeric. Am I missing something simple? I am using R 2.9.0 on Windows

The stored numbers are correct. They are rounded on printing. print(RevFCast, digits=17) See ?options And scroll down to digits.

... and see also ?print.data.frame , the "digits" argument. See also ?str It might be worth your while spending time with an R tutorial or two that covers such topics, i.e. distinguishing between an object and various (S3) methods that "represent" it, such as print(), summary(), plot() etc. -- Bert Bert Gunter "The trouble with having an open mind is that people keep

Hi all, I''m working on a financial app, and have set up some columns in my tables as decimals with precision => 8 and scale => 2. My migration looks like: change_column :lineitems, :price, :decimal, :precision => 8, :scale => 2 change_column :payments, :amount, :decimal, :precision => 8, :scale => 2 I''ve run the migration and restarted the server.

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

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/.
