I have a need to find the order of number to get a scaling parameter as a
power of 10. I have a function that works *so far*, but it is ugly and
probably buggy. In the interest of avoiding code-based outliers in my
data, I thought I would ask if anyone here has a better way.
> scl <- function(x){
+ length(charToRaw(format(trunc(x), scientific = F)))-1}
> a <- 123456789
> b <- 1E15
> c <- 12.345
> scl(a)
[1] 8
> scl(b)
[1] 15
> scl(c)
[1] 1
Thanks
