vb.net – 舍入到2.5的增量?

我需要将值舍入到最接近的2.5的倍数.

例如:
6 – > 7.5
7.6 – > 10
等等

这似乎是最好的方法吗?

Function RoundToIncrement(ByVal originalNumber As Decimal, ByVal increment As Decimal) As Decimal

        Dim num = Math.Round(originalNumber / increment, MidpointRounding.AwayFromZero) * increment
        If originalNumber Mod increment <> 0 And num < originalNumber Then
            num += increment
        End If
        Return num

    End Function
将数字除以2.5,向上舍入到最接近的整数,然后将结果乘以2.5.

你很亲密

Function RoundToIncrement(ByVal orignialNumber As Decimal, ByVal increment As Decimal) As Decimal
    Return Math.Ceiling( orignialNumber / increment ) * increment
End Function

Math.Ceiling将始终向上舍入非整数,因此您不需要进行后期调整.
