Voila j'effectue les operations suivantes pour arrondir un nombre à 10^-5 :

double a=0.000427;
a *= 100000;
a = (int)(a+.5);
a /= 100000;

Lorsque je decide d'afficher le resultat apparait alors : 4.30E-04

Or j voudrait que s'affiche 0.00043

Merci beaucoup.

Everyone thinks of changing the world, but no one thinks of changing himself | It is the peculiar quality of a fool to perceive the faults of others and to forget his own | Early clumsiness is not a verdict, it’s an essential ingredient.
