FuzzyCalc is a calculator which dispenses with the details.
You may be familiar with so-called "fuzzy clocks" which display the time in a human-friendly way such as "about 10 past 3", "late morning" or "hometime". Why should it be just people who want to know what time it is have all the nice approximations?
FuzzyCalc is a simple calculator which will round the number displayed to an appropriate amount. Three people splitting a bill for 78.56? Easy with FuzzyCalc, the answer is "25, more-or-less"! The ratio of the circumference of a circle to its diameter? "3 ish."
Maths is so much less stress this way, although I wouldnt recommend getting in any kind of engineering project designed with FuzzyCalcs assistance.
