So making a computer calculate a circumference we'll get an error (if we won't use π directly), which will be negligible for our goals.Ĭomputer can gives us a precise result if we don't need a very deep precision. But remaining ones are enough to rebuild the original?Īn interesting field of application runs around the numerical calculus, a frightening expression to indicate a mathematical approach to problems solutions based on numbers and their interpolation (a kind of unification) and not on classical functions.Īnd this is perfect when informations (any kind) must be represented onto a computer, which has by definition a limited amount of memory where to put data (information is data representation).Ī quick example: mathematical constant π has infinite numbers after decimal point a computer can storage only a limited quantity. In other words, some informations are lost: a truly necessary compromise. It's impossible you have to retain just some important points, but not all.
Think when you have to remember something, a good old friend you still don't meet since many years: how could you preserve the last record? but above all, how could you record every his/her single particular? In every-day life compromise is a good way to go on not only with people but in interaction with our world.
