That's only an error if you use the Meridional definition, which was only the standard from 1791 till 1795. After that the reference bar itself was the definition.
Feet was in practice still measured in body parts at that time, and later too. There were also tens of different highly inaccurate references in various countries. Thomas Jefferson proposed an (again, inaccurate) definition based on a pendulum, but it never even got legislated. Doing any sort of accurate scientific workin feetwas ridiculous. It only became somewhat usable after 1958when it wasdefined in terms of the meter.
Anyway, I never intended to turn this into a metric versus imerial discussion (since there really is no discussion). I was just surprised to see a scientist use miles and feet.
Aremy suggestions for 128-bit arithmetic useful to you for efficient emulation or do you require even higher performance?

All I am saying is the same arguments against supporting REAL(16) can be applied against supporting REAL(8). And then degrade the argument to REAL(4). Note, many of the GPU's, until recently, supported only REAL(4). It was pressure by those using GPUs for numerical intensive applications that drove the GPU vendors into supporting REAL(8). I am just a squeaky wheel.
