Displaying 4 results from an estimated 4 matches for "strn".

Arbitrary Precision Numbers
...0(2^n))
for (i in seq(e,0,-1)) {
s <- s + (((2^n) %/% 10^i) %% 10)
}
s
}
The above doesnt work, as I am using an integer modulus which has
insufficient precision. so I tried to coerce R to produce a full-precision
integer and sum the digits of that:
bsum2 <- function(n) {
s <- 0
strn <- formatC(2^n, format="fg")
sum(as.numeric(strsplit(strn,"")[[1]]))
}
This also doesnt seem to work. Is there another way I can do this in R?
Cheers
Rory

[PATCH 1/1] : PCI detection code doesn't corrupt memory anymore
From : Erwan Velu <erwan.velu at free.fr>
This patch fixes the pci detection stuff demo'd in pcitest.c32
- Fix a wrong type in malloc
- Incorrect use of strdup
This two fixes makes pcitest.c32 working far better, no more crash when
running it twice.
I'd like to thank Sebastian Herbszt for its reports and tests.
This patch was made for 3.62-pre16 but applies fine on 3.63-pre1.

We want to use strcmp in examples. They don't follow the ordinary
code conventions used in the rest of libguestfs.
There's something wrong with...
