In the help page for ?is.integer, there is this function
is.wholenumber <-
function(x, tol = .Machine$double.eps^0.5) abs(x - round(x)) < tol
A quick question: is there a case where this alternative function will not
work?
function(x) x %% 1 == 0
Best,
Adrian

Hi,
0x10L
returns: int 0
I would expect: int 16?
This happens with all integer constants given by hexadecimal notation.
It's a bug?

Certainly looks like one; I've cc'd this to the bug list (but won't be
able to look into fixing it).

This works correctly on Linux. The problem is that the author assumed
that atof handles hexadecimal, which it does for a C99 compiler but not
apparently on MinGW.
We have a workaround for this in mkFloat, and need to use that for the 'L'
suffix case too.
