> With IEEE FP numbers, the product of the smallest and biggest non-null non-infinite numbers is no longer approximately 1, but it is approximately 4. This is just wrong? The largest Float64 is 1.7976931348623157e308 and the smallest is 5.0e-324 They multiply to ~1e-16.

>the smallest is 5.0e-324 That's a subnormal [1]. The smallest normal double is 2.22507e-308: DBL_MIN = 2.22507e-308 DBL_TRUE_MIN = 4.94066e-324 [1] https://en.wikipedia.org/wiki/Subnormal_number https://en.wikipedia.org/wiki/Subnormal_number
