Converting non-32-bit integers from python to R to use bit64: reticulate
Thank you Gabriel for valuable insights on the 64-bit integers topic. In addition, my statement was wrong, as Python3 seems to have unlimited (and variable) size integers. Here is related CPython Code: https://github.com/python/cpython/blob/master/Objects/longobject.c Division between Int-32 and Int-64 seems to only happen in Python2.

Converting non-32-bit integers from python to R to use bit64: reticulate
Thank you Martin for giving to know and developing 'Rmpfr' library for unlimited size integers (GNU C GMP) and arbitrary precision floats (GNU C MPFR): https://cran.r-project.org/package=Rmpfr My question is: In the long term (For R3.7.0 or R3.8.0): Does it have sense that CMP substitutes INTSXP, and MPFR substitutes REALSXP code? With this we would achieve that an integer is always an

Precision of values > 53 bits
Hi, I am working with large numbers and identified that R looses precision for such high numbers. The precision is lost exactly when the number is equal or larger than 53 bits. See the following output which shows that the numbers below 53 bit have proper precision: > 2^53 [1] 9007199254740992 > 2^53-1 [1] 9007199254740991 > 2^53-2 [1] 9007199254740990 Now, see the numbers above 53

Building hdf5 for ms-windows
I am trying to build hdf5 for ms-windows. I downloaded the hdf5_1.4.7.tar.gz, gunzipped it and got a tar file. I extracted everything into a directory tree called hdf5. I also found a Makevars.win and libhdf5.def in the R help archives from March 2002. I put those two in hdf5 as well. I issued the command Rcmd build --binary hdf5 but got this message complaining it can''t find

linking hdf5, requires setting LD_LIBRARY_PATH
I am writing an R package to interface to hdf5 files (yes I know one exists, the issue will be demonstrated using that package). I tend to like to build/install things locally so that aspects of the system I am working on don't cause problems later when attempting to install elsewhere. To this end, I build and install the hdf5 libraries w/out incident: tar xzf hdf5-1.8.4.tar.bz2 cd hdf5-1.8.4

How to menage decimals in order to obtain accurate estimates
Hi, I'm trying to calculate some functions loop, unfortunately my data are decimal numbers that not allow me to get an accurate estimate. I do not want to use neither "round "nor "signif" but I would prefer to have all the information available, (the function loop is generic so you should adapt to all data, not just those in particular). The approximation error is

hdf5 package segfault when processing large data
Hi there, I am currently working on something that uses hdf5 library. I think hdf5 is a great data format, I've used it somewhat extensively in python via PyTables. I was looking for something similar to that in R. The closest I can get is this library: hdf5. While it does not work the same way as PyTables did, but it's good enough to let them exchange data via hdf5 file. There is just 1

Fixing the HDF5 package: the on.exit mystery
Dear all, I'm trying to fix a subtle bug in the hdf5 package. This package provides an interfaces to the HDF5 library and hence allows one to load data into R from files in the HDF5 format. The bug appeared during a period in which R changed but the package did not. I include below both the R and C code, stripped of everything except what is needed to show the bug. What is supposed to
