HP calcs are really not that accurate..

How can you possibly measure something that accurately?

256 digits are far more than you'd need to represent the diameter of the universe in terms of the planck length.

256 digits may be an overkill when dealing with physics problems, but there are other problems where they may be not enough.

Some authors have used the double-exponential quadrature method to compute some definite integrals and then the PSLQ algorithm to ascertain closed form solutions involving elementary functions and well know constants that solve such integrals. Such approach relies on computing such definite integrals with a large number of digits, not in the hundreds, but in the thousands. So in this universe do exist interesting problems that demand high digit counts.

Thus, apparently, you only needed 2 digits to measure your plot in square planks.
