How to convert the price of the int64 form spot to the real price of the double form？
How to convert the price of the int64 form spot to the real price of the double form？
26 Jul 2019, 17:52
I received the spot from the server ，the spot is an integer in the form of int64. We all know that the real price is a double floating point number.
for example。
EURUSD： Spot： 111298 double：1.11298
ProtoOASymbol.digits is 5
so,I usually convert the spot to a real double using the value of ProtoOASymbol.digits
But. There are some problems on GBPJPY.
the spot from the server is 13472100 ,and ProtoOASymbol.digits is 3. I know that its real price is 134.721
so ， How to convert? Maybe you can tell me to remove the 2 zeros from the back.
This is obvious，But in this case, I have to do a separate treatment for each currency pair.
And I'm not sure if there is a spot value for a currency pair that is 134721000 9-digit value。
so，Is there any general way to do this conversion?

Use spot price * 10^(-Symbol Digits).

That's what I thought. But this method is useless for certain currency pairs. For example, GBPJPY， Is it a bug in the spot value of the GBPJPY?
GBPJPY : spot is 13472100 , ProtoOASymbol.digits is 3,
spot price *10^(-Symbol Digits). = 13472100 * 0.001= 13472.1

I found that all currency pairs related to the yen and USDHUF have this problem. Its spot value is always 2 more zeros.
The correct conversion formula should be ：
spot -》 double = spot price *10^(-（Symbol Digits+2) ）.
Is this a server bug? Either the spot value is wrong or the Symbol.Digits is wrong?
