Hi, I am trying to do some calculations turning DMS data to decimal degrees using the formula (D+(M/60)+(S/3600)), some of the D's involve -ve numbers, the easiest way to do the calculation is to use absolute numbers then use the 'sign' function in R to change the answer back to the correct -ve or +ve, for example, if; D<--69 M<-8 S<-10 t...

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...

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.

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 trying to use the regexpr function to locate the decimal in a character string. Regardless of the position of the decimal, the function returns 1. For example, > regexpr(".", "Female.Alabama") [1] 1 attr(,"match.length") [1] 1 In trying to figure out what was going on here, I tried the below command: > gsub(&quot...

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,...

...be true [1] FALSE > (4.230-2.230)==2.000 <------- should be true [1] FALSE > (4.230-2.230)==2.00 <------- should be true [1] FALSE > (4.230-2.23)==2.00 <------- should be true [1] FALSE I have tried these on both 64 and 32-bit machines. Surely R should be able to do maths to 2 decimal places and be able to test these simple expressions? The problem occurs as in the 16th decimal place junk is being placed by the FPU it seems. I have also tried: > (4.2300000000000000-2.230000000000000) == 2 [1] FALSE > a <- (4.2300000000000000-2.230000000000000) > a == 2 [1] F...

Hello. Where is there an Agile Messageboard? On the first part of the Depot example, a price field shouldn''t be an integer right? (it should be more of a float since a price has decimals) Dominic Son -- Posted via http://www.ruby-forum.com/.

Hi all: I need an instruction that can convert decimal values into floating point numbers. i.e. say I have a decimal number 1110794174 (== 42355FBE in hex ) and (== 45.3435 as a float) essentially the mantissa and exponent representation needs to be used. Is there any way of doing this in llvm? Thanks and Regards -- -- Aparna Kotha Gradua...

Hi, I have a float that often looks like somthing like 2003.2 in my controller (1 decimal place) Is there a way to always show it to 2 decimal places eg 2003.20 ? Thanks Scott -- Posted via http://www.ruby-forum.com/.

When estimating values ??each determined similarly, and in which get to them by algebraic operations in some cases, are rounded with 0 decimal places and in other cases with 2 or 3 decimal places.

I have a question for our European readers: how common is it to use commas as decimal points in spread-sheet and statistics applications? Is it an inconvenience to require that all data use a period as decimal point? (i.e., 3.14159 rather than 3,14159). We're trying to make our program as foolproof as possible, and would prefer not to give users a chance to have commas as bo...

Dear all, I have some trouble with the number of decimals in R (currently R 2.9.0). For instance: > options()$digits [1] 3 let me hope that I will get three digits where useful when a number is printed.
