If one could just leave it at that, they wouldn't have put an "inexact"

flag in IEEE 754!

algorithm:

Actually, the fast divide by 10 algorithm is discussed in the *latter*

location as well.

What is calculator-style floating-point? Where (say) 15 digits are

calculated but only 12 displayed?

Although that certainly is a feature of floating-point arithmetic on

many calculators, and an entirely legitimate one, I was just referring

to decimal floating-point in general, as opposed to binary floating

point, which rather more often proves itself not to be doing what we

might expect.
