我想使用 vb.net 用小数执行基本计算。
Dim a As Single= 7200.5
Dim b As Single= 7150.3
Dim c As Single= a - b
'Expected result = 50.2
MsgBox(a.ToString + " - " + b.ToString + " = " + c.ToString.Trim)
'Produced result is: 50.2002
Dim single1 As Single
Dim single2 As Single
Dim single3 As Single
single1 = 425000
single2 = 352922.2
single3 = single1 - single2
'Expected result is: 72077.8
MsgBox(single3.ToString)
'Produced result is: 72077.81
这么简单的计算，结果怎么会这么不准确呢？当我将数据类型更改为 时，问题解决了Decimal，但Decimal对象消耗了更多内存（16 字节）。是否有任何替代数据类型可用于执行具有准确结果的简单分数计算？
