signif() + datatable() bug #1127
Comments
I think this is a problem on htmltools or htmlwidgets's side. The data is correct on DT's side: > x = DT::datatable(signif(data.frame(3.234866680561728e-127), 3))
> str(x)
List of 8
$ x :List of 6
..$ filter : chr "none"
..$ vertical : logi FALSE
..$ data :'data.frame': 1 obs. of 2 variables:
.. ..$ : chr "1"
.. ..$ X3.23486668056173e.127: num 3.23e-127
[...] but > str(htmlwidgets:::toHTML(x))
List of 3
$ :List of 3
..$ : NULL
..$ :List of 3
.. ..$ name : chr "div"
[...]
$ :List of 3
..$ name : chr "script"
..$ attribs :List of 2
.. ..$ type : chr "application/json"
.. ..$ data-for: chr "htmlwidget-6b6194a1b92c04b274c8"
..$ children:List of 1
.. ..$ : 'html' chr "{\"x\":{\"filter\":\"none\",\"vertical\":false,\"data\":[[\"1\"],[3.229999999999999e-127]],\"container\":\"<tab"| __truncated__
.. .. ..- attr(*, "html")= logi TRUE |
I see, thanks for the response. The strange thing, it doesn't happen when directly running |
Unfortunately I think this is just a natural consequence of floating point imprecision. (I couldn't reproduce > print(signif(3.23e-127, 3), digits=16)
[1] 3.229999999999999e-127 R defaults to precision of I don't know if it's a good idea to do so, but you can use |
