Rounding a variable to two decimal places C# [duplicate]
Use Math.Round and specify the number of decimal places.
Math.Round(pay,2);
Math.Round Method (Double, Int32)
Rounds a double-precision floating-point value to a specified number of fractional digits.
Or Math.Round Method (Decimal, Int32)
Rounds a decimal value to a specified number of fractional digits.
You should use a form of Math.Round
. Be aware that Math.Round
defaults to banker's rounding (rounding to the nearest even number) unless you specify a MidpointRounding
value. If you don't want to use banker's rounding, you should use Math.Round(decimal d, int decimals, MidpointRounding mode)
, like so:
Math.Round(pay, 2, MidpointRounding.AwayFromZero); // .005 rounds up to 0.01
Math.Round(pay, 2, MidpointRounding.ToEven); // .005 rounds to nearest even (0.00)
Math.Round(pay, 2); // Defaults to MidpointRounding.ToEven
(Why does .NET use banker's rounding?)
decimal pay = 1.994444M;
Math.Round(pay , 2);
