Re: Using standardized SI prefixes

[Caeles <caeles@pcpool.mathematik.uni-freiburg.de>]

One more opinion:

If you consider a number more relevant than its nearest power of 2,
then somebody else will consider every digit of that number relevant.
In that case, don't use rounding by SI/IEC prefixes at all.
For an example see Bug #420716.

The first number, where the difference between base 1024 and base
1000 results in a greater inaccuracy than rounding to the next power
of 2, is 2^150 vs 10^45. According to the cited wikipedia article,
SI and IEC prefixes roughly go only half as far. So the difference
between SI and IEC prefixes is immaterial.
