search for: modulus

I am a statistician and I come up to an interesting problem in cryptography. I would like to use R since there are some statistical procedures that I need to use. However, I run into a problem when using the modulus operator %%. I am using R 2.2.1 and when I calculate modulus for large numbers (that I need with my problem) R gives me warnings. For instance if one does: a=1:40; 8^a %% 41 one obtains zeros which is not possible since 8 to any power is not a multiple of 41. In addition when working with number...

I'm trying to do a modulus operator in R-1.2.2 on Windows -- specific version: R : Copyright 2001, The R Development Core Team Version 1.2.2 Patched (2001-03-22) Here's what the R language manual says: "R contains a number of operators.

suppose I have following complex number : a = -0.0475983+0.5364486i This number I got as an eigen value of a matrix. Now I would like to calculate the Modulus of this complex number. Is there any function for doing that?

Dear R Helpers, I am trying to extract the modulus from divisions by a sequence of fractions. I noticed that %% seems to behave inconsistently (to my untutored eye), thus: > 0.1%%0.1 [1] 0 > 0.2%%0.1 [1] 0 > 0.3%%0.1 [1] 0.1 > 0.4%%0.1 [1] 0 > 0.5%%0.1 [1] 0.1 > 0.6%%0.1 [1] 0.1 > 0.7%%0.1 [1] 0.1 > 0.8%%0.1 [1] 0 > 0.9%...

Is there a modulus operator in R? Anna

Since we know vq->vring.num is a power of 2, modulus is lazy (it's asserted in vring_new_virtqueue()).

R users, I am having a problem with the modulus operator for large numbers as follows, a <- 2 n <- 561 ## n is the first Carmichael number, so by Fermat's Little Theorem the below should equal zero. (a^(n-1) - 1) %% n [1] 2.193172e+152 ## Seems that R and Fermat disagree ## Also, 1000000000000000000 %% 11 [1] -32 This seems like a...

Dear R friends, I was wondering if there were factorial and modulus functions out there that I've somehow overlooked? -P. -- Peter L.

Full_Name: M. Edward Borasky Version: 1.2.2 OS: both Windows 2000 and Red Hat Linux 7.1 Submission from: (NULL) (208.130.245.188) According to the R language manual, "%" is the modulus operator. However, on both Windows and Linux, I get a syntax error when I type records <- 100000 records % 1000 I tried wrapping the operands with "as.integer ()" but that didn't help either. This is version 1.2.2 of R; I haven't had a chance to try it with R-1.2.3 yet, but i...

With the default openssh configuration, the selected cipher is aes128-ctr. This means that dh_estimate gets called with bits=128, so dh_estimate selects a DH modulus size of 1024 bits. This seems questionable. Since the NSA seems to be sniffing most internet traffic, keeping SSH sessions secure against after-the-fact offline attack matters, and 1024-bit DH is not convincingly secure against well-funded adversaries. (On the other hand, 128-bit symmetric keys...

Hi, OpenSSH 6.9 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. This release contains some substantial new features and a number of bugfixes. Snapshot releases for portable OpenSSH are available from http://www.mindrot.org/openssh_snap/ The OpenBSD version is available in CVS HEAD: http://www.openbsd.org/anoncvs.html Portable OpenSSH is

Hi folks, This applies to src/share/man/man5/moduli.5 in the OpenBSD source tree, and doesn't seem to apply to the portable OpenSSH, so I've sent this change here instead of via Bugzilla. The wording of moduli(5) implies that sshd puts more thought about which modulus it selects than it really does. The following patch corrects this.

Can anyone tell me how to calculate quantiles of the studentized maximum modulus distribution using R? Thanks! __________________ Rob Kabacoff, Ph.D. www.statmethods.net [[alternative HTML version deleted]]

So I have this key information that I got by generating a private and public key in VB, but it gave it to me in the form of a modulus and exponent in an XML file. Now, I need to encrypt some stuff in ruby using that info. On this site: http://blog.internautdesign.com/2007/11/2/ruby-openssl-rsa-public-key-from-modulus-and-exponent/comments/165, they explain how to do that, but clearly this info is in integer format so I need to co...

R Developers, 1000000000000000000 %% 11 [1] -32 I now understand that integers cannot be larger than .Machine$integer.max, but because the above produces a result than is patently wrong instead of an error, I'm reporting this as a bug.
