I'm sorry for asking this stupid kind of question, but I can't understand why double variables are not printed as double. It seems, that they are truncated to a max number of digits which seems to be variable. Here an example:
>(1234567890.123456789 -> x)
[1] 1234567890
Where is the decimal digits gone? In the RStudio Environment view the value of x is being displayed as 1234567890.123456. Why does the console output differs from the environment view, and why does it differ from the values I entered?
> (567890.12345678912345 -> x)
[1] 567890.1
> sprintf("%f", x)
[1] "567890.123457"
The .Machine settings for double are these
> .Machine$double.xmin ; .Machine$double.xmax
[1] 2.225074e-308
[1] 1.797693e+308
and here the complete list of the .Machine content

Thanks for any support Wasili
