Default Re: Got my calculator to lie

Just lucky that the 32 digits carried in the Windows calculator happen to have been sufficient this time around. But it isn't that the Windows calculator is all that much smarter!

The windows calculator makes this claim:

Extended Precision, a feature of Calculator, means that all operations are accurate to at least 32 digits. Calculator also stores rational numbers as fractions to retain accuracy. For example, 1/3 is stored as 1/3, rather than .333. However, errors accumulate during repeated operations on irrational numbers. For example, Calculator will truncate pi to 32 digits, so repeated operations on pi will lose accuracy as the number of operations increases.
