   > Are you worried about the decimal point? In fact, int32 or Int64 contains 
integer and decimal parts, so precision and data will not be lost. You can take 
a look at Java's `BigDecimal`, which is also saved with Int64.
   
   Yes indeed, I was worried about that. Ok I did not know that int32 or Int64 
contained both unscaled value and scale. Thanks for the information.
   
   Thanks also for merging
