Rounding half down a decimal

Question

Does an equivalent of Java RoundingMode.HALF_DOWN exist in C#?

For example, I want to round 1.265 to 1.26, and 1.266

Answer 1

Have a look at Math.Round e.g.

  double[] tests = new double[] {
    1.265,
    1.266,
  };

  var demo = tests
    .Select(x => $"{x} -> {Math.Round(x, 2, MidpointRounding.AwayFromZero)}");

  var report = string.Join(Environment.NewLine, demo);

  Console.Write(report);

Outcome:

  1.265 -> 1.26
  1.266 -> 1.27
