Possibly confusing default for label_number_si?

[mfherman]

I've found the relatively new label_number_si() quite useful -- thanks! One thing that just caught me surprised is how it handles going from non SI to SI units. For example, at first glance, the axis below looks correct. But in fact, we get 2K because 1.5K is being rounded up as the default accuracy is 1.

library(scales)

demo_continuous(c(0, 1500), label = label_number_si())
#> scale_x_continuous(label = label_number_si())

Taking the accuracy to 0.1 works, but then you get the unnecessary decimal places at 0 and 500.

demo_continuous(c(0, 1500), label = label_number_si(0.1))
#> scale_x_continuous(label = label_number_si(0.1))
