Rounding up to 2 decimal places in C#

Rounding up to 2 decimal places in C#

In C#, you can round a numeric value up to two decimal places using the Math.Round method with the appropriate overload. The Math.Round method allows you to specify the number of decimal places to which you want to round the value. To round up to two decimal places, you can use the following code:

double value = 12.34567; double roundedValue = Math.Round(value, 2, MidpointRounding.AwayFromZero);

In this example, the variable value contains the original number (12.34567). The Math.Round method is used to round this value to two decimal places. The second argument 2 specifies the number of decimal places, and the third argument MidpointRounding.AwayFromZero ensures that rounding is done away from zero, which means values exactly midway between two rounded values will be rounded up.

After executing the above code, the roundedValue variable will have the value 12.35, which is the original value rounded up to two decimal places.

Keep in mind that Math.Round returns a double data type, so if you need the rounded value in string format with exactly two decimal places, you can use formatting like this:

string formattedValue = roundedValue.ToString("0.00");

The formattedValue will now be the string representation of the rounded value with two decimal places (e.g., "12.35").
