Euclid is a calculator and so much more. One of its unique features is
that it preserves numbers in their natural state, rather than forcing
everything into decimal form. For example, it remembers that 1/3 is
1/3, not 0.33333... Thus, (1/3) * 3 = 1, as it should (try this on most
digital calculators and you're bound to get the incorrect 0.99999...
Euclid also supports matrix operations and sets.
25 March 2006
