Dim sr As Double = DataTables("明细账").Compute("sum(收入)","[流水编号] = 'R1702000114'")

Dim zc As Double = DataTables("明细账").Compute("sum(支出)","[流水编号] = 'R1702000114'")

Output.Show(sr)

Output.Show(zc)

Dim ye As Double = sr - zc

Output.Show(ye)

Dim rt As DataRow = DataTables("日记账").Find("[流水编号] = 'R1702000114'")

Dim ls As Double = rt("支出")

Output.Show(ls)

Dim ye1 As Double = ye + ls

Output.Show(ye1)

Dim sz111 As Double = -988.83 + 988.83

Output.Show(sz111)

Dim sz2 As Double = ye * -1

Output.Show(sz2)

If sz2 <> ls Then

Output.Show("不等")

Else

Output.Show("相等")

End If

执行结果：

2666.33

3655.16

-988.83

988.83

1.13686837721616E-13

988.83

不等

红色的结果，程序怎么的出来的？

好像是格式问题！

求指路！！！！
