Fonctionnement détaillé.
SIERREUR est une fonction indispensable d'Excel. Renvoie une valeur personnalisée si une formule génère une erreur ; sinon, renvoie le résultat normal. Elle permet d'automatiser vos tableaux, fiabiliser vos calculs et gagner un temps précieux au quotidien dans vos feuilles de calcul.
💡 En résumé simple.
Runs a formula, but if the formula fails (like a division by zero error), it gives a clean default value instead of Excel's ugly errors.
"Think of this like a protective shield. If your math equation tries to divide by zero and would explode with a weird error, the shield turns it into a friendly 0."
