+  Don't compute numbers if even, we know they'll go to 1
+  (https://smunix.github.io/dev.stephendiehl.com/hask/tutorial.pdf - Scientific numbers)
+
+  Sample a few numbers at a given order of magnitude, then increase the exponent and sample more numbers
+  eg. [-10..n..+10], where n = 2^1_000, then n = 2^1_001, then n = 2^2_000, etc.
