We have calculators that work 99.99% of the time. I am not sure of it makes sense to settle for 90% just because we could.
Where have you seen a calculator that gives the wrong answer 0.01% of the time?
That would be unheard of.
How about 1 in 9 billion?

that's true. instead they (device dependent) butcher calculations by accumulating arbitrarily large numerical error and/or by using binary floating point math, which is so much better... /s
