Simon's comments add another viewpoint to mine. My own knowledge of the
impact of "disable-long-double" does not include an understanding of
exactly what effect this has. One needs to spend a lot of time and effort
with excruciating details. Fortunately, we can usually get away with

80 bit registers (I don't have my original docs with me here in Victoria)
seem to have been part of the 1985 standard to which I was one of the 31 named
contributors. See

For cases like these, I think it would be more useful to have some
mechanism for associating URLs / hosts with credentials, and have R use
those credentials by default whenever accessing those URLs. Since
download.file() now supports custom headers, this could be a mechanism for

Hi John.
I don't think the 80 bit format was part of IEEE 754; I think it was an
Intel invention for the 8087 chip (which I believe preceded that
standard), and didn't make it into the standard.
The standard does talk about 64 bit and 128 bit floating point formats,
but not 80 bit.

I think I had that problem with the minimaxApprox package as well.

Slightly tangential: I had some woes with some vignettes in my
optimx and nlsr packages (actually in examples comparing to OTHER
packages) because the M? processors don't have 80 bit registers of
the old IEEE 754 arithmetic, so some existing "tolerances" are too
small when looking to see if is sma

Hi,
I wanted to ask if people have good advice on how to debug M1Mac package
check errors when you don´t have a Mac? Is a cloud machine the best option
or is there something else?
Thanks
