For example, assume that we want to calculate the sum of the square roots of all integers between 1 and 10 inclusive. We write a simple program called sigmasqrt (please see source code) which does exactly that. ###>Par exemple, si nous voulons calculer la somme des racines carrées de tous les entiers inclus strictement entre 1 et 10, nous écrivons un simple programme appelé sigmasqrt (voir code source) qui fait cela exactement.
