[R] as.numeric looses precision

[Kehl Dániel]

Hi Roger,

I think it does! Try multiplying with 1000000 or similar. It is just a matter of displaying your result.

Tárgy: [R] as.numeric looses precision

I have a string that contains a number and when I convert it to a number I loose precision and I would like to know if there is a way to avoid that.  Here is my example:

p <- "1087.003489"
as.numeric(p, digits=6)

R gives me 1087.003:

> p <- "1087.003489"
> as.numeric(p, digits=6)
[1] 1087.003

I would be nice if I could keep all the decimal places after the conversion.

Thanks,

Roger
