示例1: Sample
' This example demonstrates the Math.Round() method in conjunction
' with the MidpointRounding enumeration.
Class Sample
Public Shared Sub Main()
Dim result As Decimal = 0D
Dim posValue As Decimal = 3.45D
Dim negValue As Decimal = -3.45D
' By default, round a positive and a negative value to the nearest even number.
' The precision of the result is 1 decimal place.
result = Math.Round(posValue, 1)
Console.WriteLine("{0,4} = Math.Round({1,5}, 1)", result, posValue)
result = Math.Round(negValue, 1)
Console.WriteLine("{0,4} = Math.Round({1,5}, 1)", result, negValue)
Console.WriteLine()
' Round a positive value to the nearest even number, then to the nearest number
' away from zero. The precision of the result is 1 decimal place.
result = Math.Round(posValue, 1, MidpointRounding.ToEven)
Console.WriteLine("{0,4} = Math.Round({1,5}, 1, MidpointRounding.ToEven)", _
result, posValue)
result = Math.Round(posValue, 1, MidpointRounding.AwayFromZero)
Console.WriteLine("{0,4} = Math.Round({1,5}, 1, MidpointRounding.AwayFromZero)", _
result, posValue)
Console.WriteLine()
' Round a negative value to the nearest even number, then to the nearest number
' away from zero. The precision of the result is 1 decimal place.
result = Math.Round(negValue, 1, MidpointRounding.ToEven)
Console.WriteLine("{0,4} = Math.Round({1,5}, 1, MidpointRounding.ToEven)", _
result, negValue)
result = Math.Round(negValue, 1, MidpointRounding.AwayFromZero)
Console.WriteLine("{0,4} = Math.Round({1,5}, 1, MidpointRounding.AwayFromZero)", _
result, negValue)
Console.WriteLine()
End Sub
End Class输出：
3.4 = Math.Round( 3.45, 1) -3.4 = Math.Round(-3.45, 1) 3.4 = Math.Round( 3.45, 1, MidpointRounding.ToEven) 3.5 = Math.Round( 3.45, 1, MidpointRounding.AwayFromZero) -3.4 = Math.Round(-3.45, 1, MidpointRounding.ToEven) -3.5 = Math.Round(-3.45, 1, MidpointRounding.AwayFromZero)
