Hm. When I unpack those two values, they are distinctly different:

printf "%17.17f\n", unpack 'd', pack 'b64', '1001110001010011100010111001000010000101000001010110011000000010';; 181.01965800261112000 printf "%17.17f\n", unpack 'd', pack 'b64', '1010110001010011100010111001000010000101000001010110011000000010';; 181.01965800261101000 $first = unpack 'd', pack 'b64', '1001110001010011100010111001000010000101000001010110011000000010';; $second = unpack 'd', pack 'b64', '1010110001010011100010111001000010000101000001010110011000000010';; printf "%f %f ;> %17.17f\n", $first, $second, $first - $second;; 181.019658 181.019658 ;> 0.00000000000011369

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
