I would set the Double as the default setting and sell it as the "standard precision".. :)

First of all you should quote Wolfram's result correctly.

And second: Your suggestions faintly reminds me on frequency meter ads in US-American electronic magazines I saw in the Eighties of last century, where some devices were shamelessly advertized as ppm or ppb meters just because they displayed the appropriate number of digits. No, what we're "selling" are real world calculators for real world problems - and IMHO even our single precision implemented covers most of them. Just compare the precision of physical constants (published e.g. by NIST) and you will know where the real world ends so far.
