bench_exp(min, max, base = 10)

public

Returns a set of ranges stepped exponentially from min to max by powers of base. Eg:

bench_exp(2, 16, 2) # => [2, 4, 8, 16]

# File lib/minitest/benchmark.rb, line 28
    def self.bench_exp min, max, base = 10
      min = (Math.log10(min) / Math.log10(base)).to_i
      max = (Math.log10(max) / Math.log10(base)).to_i

      (min..max).map { |m| base ** m }.to_a
    end
