Example:

julia> format.(logrange(1.2e-12, 1.2e12, 25); autoscale=:metric)
25-element Vector{String}:
 "1.2p"
 "0.012n"
 "0.12n"
 "1.2n"
 "0.012μ"
 "0.12μ"
 "1.2μ"
 "0.012m"
 "0.12m"
 "1.2m"
 "0.012"
 "0.12"
 "1.2"
 "12"
 "120"
 "1.2k"
 "12k"
 "120k"
 "1.2M"
 "12M"
 "120M"
 "1.2G"
 "12G"
 "120G"
 "1.2T"

Specifically, instead of results like "0.012n" and "0.12n" I expected "12p" and "120p".

Test coverage only hits exponents which are multiple of 3. I don't know what the intended behavior is. My expectation is from using the ENG mode of HP RPN calculators.

Is this a bug or am I applying the wrong prior?
