Android Question multiplying doubles and long

[ViMeAv ICT]

Dim nVal As Long
Dim nPrice As Double

nPrice = 8.95
nVal = nPrice * 100

nVal returns 894.

How is this possible?
If I use 2.95, it's okay. (or all other numbers I have tested until now)

I've been through it many times. In a accounting calculation program I realized I had many problems for this error.

Now I pass the double in the string and shift the decimal decimal point with the string to not have any calculation errors.

Dim nVal As Long
Dim nPrice As Double
Dim S as string

nPrice = 8.95
S=nPrice
nVal = S.Replace(".","")

In our apps where we have money amounts, float values are used only for display. Everything is stored and computed as integers (or longs).
e.g. 1.37 (display) = 137 (integer)

Yes, but I understand it too late..
