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

Hi, I have some values on my webpage displaying like 1.22333333333 2.33333344444 2.33377777777 etc. Here I want to display values upto 2 decimal places correct. i.e, 1.22333333333 should be dislayed as 1.22 2.33333344444 should be dislayed as 2.33 2.33777777777 should be dislayed as 2.34 & so on.... How to do this in ruby????? Is there any function??? Thanx in advance. Prash --

Hello CentOS List Members, Thoughts as to why my BC functions aren't properly converting between bases? Decimal to binary or hex works fine, but not binary or hex to decimal and so forth. No doubt the syntax is in some way wrong, but when I test from the CLI and the right values are returned, I have to wonder. Other than a few other define statements, the only other option I have set is

I'm not an expert in bc, so I might be wrong, but it looks like setting the ibase inside a function is simply too late. ibase affects how bc interprets input. So

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 Graduate Student Electrical and Computer Engineering

Hi R masters, Sorry for first mensage, this is orignal text... y<-c(2.8150,3.5239,4.0980,4.5845,5.0709,5.4824,5.8427,6.3214,6.7349,7.3651) x<-c(37,42,47,52,57,62,67,72,77,82) I need fit R and A in y=f(x)=R*exp(A*x), with minimize sd= sqrt(SRR/(n-2)) where SRR is Sum of the Square of the Residuals and n is number of data points (in this case 10) How do I make this? Thanks in advance

Hi all, I have a numeric vector with 1 decimal place, and I'd like to extract the last 3 characters, including the decimal point. The vector ranges from 0 to 20. x <- round(runif(100)*20, digits=1) Some of numbers have 3 characters, and some have 4. I've read up on the substr() function but that extracts characters based on exact positions. How can I extract just the last 3

I have a string '982323.1' and would like to replace everything after the '.' with a '41'. So the string should look like '982323.41'. The code I use to do this is sub('\.$','41',982323.1) This works fine as long as there is only 1 digit after the decimal. If I have '982323.10', then the result of the code is '982323.141'

Hi there, could somebody help me to convert a decimal number into a hexadecimal number? I know that there is the function "sprintf", but the numbers I want to convert consist of 20 or more numbers. "Spintf" is not able to convert these big numbers. Thanks for any help. Antje [[alternative HTML version deleted]]

Is there a straightforward way to convert character information from decimal representation to the octal one used by R? I'd like something like a function ascii(number,base=10), such that > ascii(91) [1] "\133" I can easily do the mapping from 91 to 133, but what is a good way to operate on 133 to deliver "\133"? Would a lookup table be a better solution? David
