similar to: Simple addition and subtraction doesn't work??

hello, today while trying to extract data from a list for subsequent analysis, i stumbled upon this funny behavior on my system: > x<-c(0.1,0.9) > 1-x[2] [1] 0.1 > x[1] [1] 0.1 > x[1]==1-x[2] [1] FALSE > x[1]>1-x[2] [1] TRUE > x<-c(0.3,0.7) > x[1] [1] 0.3 > x[2] [1] 0.7 > 1-x[2] [1] 0.3 > x[1]==1-x[2] [1] FALSE but: >

Ok, I am sure this is a simplistic problem that I am just missing right now (maybe eyes are crossed??). However, I am trying to do simply math here. I have these variables initialized as follows: @amount_due = @amount_paid = @total_due = 0.0 I get @total_due and it is set to 1739.6 from the database. I then get @amount_paid and it is set to 1739.6 from the database. I then calculate the

Hi all, I am writing a custom backend. Doing more testing i notice that for some reason something like: int test(int x) { return x - 1; } is being turned into this IR: ; Function Attrs: nounwind define i32 @test(i32 %n) #0 { entry: %n.addr = alloca i32, align 4 store i32 %n, i32* %n.addr, align 4 %0 = load i32* %n.addr, align 4 %sub = sub nsw i32 %0, 1 ret i32 %sub } But finally in

OK, this is very elementary, but I need help. I have looked in Verzani, past postings etc. Problem: I need to subtract the "length" date between "h4" and "a3" #which would be 4-1 I would rather not convert the two columns into four columns (with headings being "a3","a4","c4","h4"). DF <- data.frame(length=c(1,2,3,4),

seq(0.1, 0.9 - 0.8, by = 0.1) gives the following error message: Error in seq.default(0.1, 0.9 - 0.8, by = 0.1) : wrong sign in 'by' argument but seq(0.1, 0.8 - 0.7, by = 0.1) gives [1] 0.1 (no error message) Why do I get an error message in the first case?

Dear David Techer, I have read through your article on Xen VGA passthrough on http://www.davidgis.fr. It appears that the following command on your blog doesn''t work. dmesg | grep 01:00.0 | grep BAR The above command shows nothing at all. Is there an alternative solution? Thank you very much. Yours sincerely, Teo En Ming (Zhang Enming)

Hi All, I followed the instructions here at http://bderzhavets.wordpress.com/2009/06/10/setup-fedora-11-pv-domu-at-xen-3-4-1-dom0-kernel-2-6-30-rc6-tip-on-top-of-fedora-11/ However, when I do a "make menuconfig", I cannot see any XEN related configuration options. What am I missing? Thank you. Mr. Teo En Ming Dip(Mechatronics Engineering) BEng(Hons)(Mechanical Engineering)

Hi Yongjie, I have just compiled and installed Xen 4.3-unstable changeset 26666 and Linux kernel 3.8.1, according to your specifications. However, I still cannot get success with Intel HD Graphics 4600 IGD VGA passthrough. Although in Device Manager in Windows 7 HVM domU, it says "This device is working properly" for Intel HD Graphics 4600, I can only get 16 colors. Please refer to

Dear Intel Engineers, I am unable to get Intel integrated graphics (IGD) VGA passthrough to work with Xen 4.0.1-rc6-pre, Xen 4.0.1-RELEASE, pv-ops dom0 kernel 2.6.32.19 and 2.6.32.21.

What are the plans for 2.6.37 merge window? I believe at least: - Xen PCI frontend Others? I''m going to
