Re: [R] How to improve accuracy of output?

2022-05-24 Thread Rui Barradas

Hello,

I cannot reproduce this print behavior, with digits=14, there are 14 
digits printed.



x <- c(98.718527356108, 103.10265923704)
x
#> [1]  98.71853 103.10266

old_dig <- options(digits = 14)
x
#> [1]  98.718527356108 103.102659237040

options(old_dig)


Maybe there's something else going on?

Hope this helps,

Rui Barradas

Dear Forum
In my code, I am trying to compute Value at risk.
I have an issue as mentioned below:
I have defined


options(digits = 14)
But my output is something like

   df$price

[1] 98.7185273         103.10265923  
However, if use Excel, I get values as
98.718527356108 103.10265923704
and so on.
Is there any way I can improve on R output accuracy.
Problem is If I use
options(digits = 20)
I still get same prices as when I was using options(digits = 14) and on the 
other hand my confidence level value, which should be equal to 0.99, gets 
distorted to 0.9899 impacting  Value at Risk value.
Please guide

I think you have to use print(df$price, digits = 14)
