VB中用double值居然被溢出了.郁闷ing

[coolrit]

Dim NowH As Double
Dim sTime As String

sTime = Format(Hour(Now), "00") + Format(Minute(Now), "00") + Format(Second(Now), "00")
For i = 0 To 6 Step 1
NowH = TimeChangeToNum(sTime) - (6 - i) * 20 * 60
If NowH < 0 Then
NowH = NowH + 24 * 3600
End If
Next i


NowH居然被溢出了,
用监视器查看的时候nowh=-5537

[chinaren502]

TimeChangeToNum(sTime) - (6 - i) * 20 * 60
改成
cdbl(TimeChangeToNum(sTime) - (6 - i) * 20 * 60)

没有错的!真正NowH并不是Double
最好用一个函数转成Double的!
NowH=NowH+24*3600
这句默认把NowH转成了Integer
所以改成
NowH=NowH+24*3600.0好像可以了!
