Machine epsilon of the HP Prime

[EdS2]

Ah, thanks, so I may not be fully compliant, but I am a recognised variant!

Quote:This alternative definition is much more widespread outside academia: machine epsilon is the difference between 1 and the next larger floating point number.

This, also from the Wikipedia page, seems to me to cast doubt on this approach:

Quote:The following simple algorithm can be used to approximate the machine epsilon, to within a factor of two (one order of magnitude) of its true value, using a linear search.
