In a way that's similar to, say, the TI-58/59: you see 10 digits but 13 are present.

So, HP 12C and 12C Platinum does totally different way of rounding ...
Is it still appropriate to compare internal precisions this way ?

Even if 12C had a million digits precision, due to rounding-back-to-10 digits, it still require 11 iterations.
