With C  String formatting you can avoid the multiplication by 100 as it will make the code shorter and cleaner especially because of less brackets and also the rounding up code can be avoided    current   maximum  ToString  0 00          Output - 16 67

You can hold onto the percentage as decimal  value   total  and then when you want to render to a human you can make use of Habeeb s answer or using string interpolation you could have something even cleaner   var displayPercentage       decimal value   total P      or    Calculate percentage earlier in code decimal percentage    decimal value   total        Now render percentage var displayPercentage      percentage P
