similar to: Rounding up to two decimal places

FWIW, it doesn't seem to be happening on Mac OS: > format(2^30, digits=0) [1] "1.e+09" > prettyNum(12345.6, digits=0) [1] "1.e+04" A glibc misfeature? -pd > On 22 Mar 2019, at 10:10 , Martin Maechler <maechler at stat.math.ethz.ch> wrote: > > Thank you, Robert for raising this here ! > >>>>>> Robert McGehee

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/.

The problem: I would like to translate the Octave algorithm in griddata.m to R. Within the griddata algorithm calls are made to the Delaunay function. For the R translation I have found delaunayn within the "geometry" package and also the deldir package. Both do similar things but give slightly different results depending on the input. The question is, what is making the results for the

"The question is, what is making the results for the R packages different from each other?" There are literally thousands of R packages, contributed independently by thousands of people. There should be no expectation of consistency or for that matter, "correctness", among them. Caveat emptor. Only within the base R distribution, maintained and mostly written by the R Core

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. What is happening? Thank you. -- View this message in context: http://r.789695.n4.nabble.com/Number-of-decimal-places-tp4647549.html Sent from the R help mailing list archive at Nabble.com.

Hello - R-experts, Is there any way with which we can specify the number after decimal point to take. Like I have a situation where the values are comming 0.160325923 but I only want 4 place to decimal say 0.1603. Is there any way for that. I am no expert in R- and this may sound simple to many.sorry Thanks for any help. With Regards Subhabrata

Good day, All, Is there any way to maintain the number of decimal places in the type of situation below? I would like to maintain the number of decimal places in 0.667, despite the fact that its column-mates have a fourth decimal place. Thank you for your time.

Hi R-List, I have a question regarding R-language formats, I think. I am producing a series of graphs (using plot, barplot, barchart, and bwplot, using either text or mtext to place values on the graphs) and tables for a Francophone country. In fact, I have already done so. However, while they are pleased with the results they've requested I convert all of my decimal points into the French

Dear R-users: Hi, I read here ( http://stackoverflow.com/questions/2287616/controlling-digits-in-r) that R is only accurate up to the 15th decimal place, despite the fact that if you choose to display more decimal places, it will. I wonder if R uses the information beyond the 15th decimal place in actual computation. Thanks! Best, Xiao [[alternative HTML version deleted]]

I am a beginner in programmin in general and R specifically. I would like to generate a set of random numbers in a normal distribution but to limit the decimal places in these numbers to only 2. I have been using x1 <- runif(1,0,1) to generate my numbers. Can I add something to it to enable me to only get results rounded off to 6 decimal places? -- View this message in context:

Hello everyone, does anybody know how to increase the decimal places that R uses to calculate something. I think that in default R uses 6 decimal places but I need 12. Thank you very much! Best regards, Maja! --

Full_Name: Ben Phalan Version: 2.2.1 OS: Win XP Submission from: (NULL) (131.111.111.231) I have noticed that floor returns the wrong number when there are more than 15 decimal places: > floor(6.999999999999999) [1] 6 > floor(6.9999999999999999) [1] 7 There is a similar problem with ceiling, so this may apply to all/most rounding functions? > ceiling (2.000000000000001) [1] 3 >

Hello, All, How can I maintain the decimal places when using write.table()?

Hi All: I had a basic question to ask. I am running R2WinBUGS so that I could automate the running of my model using 1000 simulated datasets. Below is the code I am using. The only problem I am having is the bugs output that comes out shows my parameters as nos with 1 decimal place after. I would want to have the parameters with 5 places after decimal. How would I specify that in my code for

How to force R to print 2 decimal places in column of a data.frame? I tried to do so: x = inp(format(rounf(inp$Tamanho, 2), nsmall = 2),) where "INP" is data.frame and "Size" is the name of column.
