round function seems to produce maximum 2 decimals
I am trying to use round()to force R to display a specific number of
decimals, but it seems to display <=2 decimals no matter what I specify in
the digits argument. As an alternative I tried signif(), but it also
produces unexpected results. See example code and results below. Format()
works, but then the result no long...

Question on Round function
I happened to see these:
> round(.5, 0)
[1] 0
> round(1.5, 0)
[1] 2
> round(2.5, 0)
[1] 2
> round(3.5, 0)
[1] 4
> round(4.5, 0)
[1] 4
What is the rule here?
Should not round(.5, 0) = 1, round(2.5, 0) = 3 etc?
Thanks and regards,

round.Date and trunc.Date not working / implemented
Technically, there is a round() for 'Date' objects, but it doesn't
seem very useful, because it basically just fall back to the default
round() method, which only takes the 'digits' argument.
Here's an example:
> date <- Sys.Date()
> class(date)
[1] "Date"
We see that there are only...

round(1.5) = round(2.5) = 2?
Dear R-users
with a bit of grief I had to repeat an extensive analysis because I
did not suspect (and therefore did not read the documentation) that
round was implemented as "for rounding off a 5, the IEC 60559 standard
is expected to be used, 'go to the even digit'", resulting in
round(1.5) = 2
round (2.5) = 2.
As a non-mathematician I am both puzzled and intrigued by this rule as
it is against what I have learned in my math c...

round.Date and trunc.Date not working / implemented
This is a workaround, and could be the basis for a round.Date improvement:
date <- Sys.Date()
as.Date(round(as.POSIXct(date), "years"))
as.Date(round(as.POSIXct(Sys.Date() + 180), "years"))

float calculation error
Hi
I have the following values
pActualCost = 33.00
pPaymentCost = 29.99
So this calculation should leave me with 0.01
pPaymentDifference = pActualCost - pPaymentCost
however when doing this in rails, it returns 0.00999999999999801
has anyone got any suggestions to whats going wrong and how I can
correct this
Thanks
Scott

- round() strange behaviour
Hi,
I am getting some strange results using round - it seems that it depends if the number before the decimal point is odd or even ....
For example:
> round(1.5)[1] 2> round(2.5)[1] 2
While i would expect that round(2.5) be 3 and not 2.
Do you have any explanation for that?
I really appreciate your input,
Monica

Problems with pf() with certain noncentral values/degrees of freedom combinations
...s of freedom
came about (PR#138), but I couldn't find the present issue reported
anywhere.
Might there be a way to make the algorithm more stable? I'm not sure how
difficult this issue might be to fix, but hopefully it won't be too bad
and can be easily done. Any thoughts on a workaround until then?
Thanks,

round to specific intervals
Dear R users/helpers,
I am wondering is there an existing function in which you can round
numbers to a set of values. I know you can use 5 * round(x/5) for
rounding to the nearest 5 or so, but what if the interval size is not
constant.
For example:
## Not run
test <- rnorm(100)
round(test, c(1, 5, 10, 20, 50))
so that the test is rounded to the closest value in the vector.
Than...
