Hello, Try this one: CString Valeur="1250.20"; int Fractional = ((atof(Valeur) - atoi(Valeur)) * 100.0); change 100 to 100.0 My month article: Game programming by DirectX by Lan Mader. Please visit in: www.geocities.com/hadi_rezaie/index.html Hadi Rezaie

Result of atof-atoi is converted to int before multiplication. Pavel Sonork 100.15206
