add two double given wrong result

Question

I\'m using the following piece of code and under some mysterious circumstances the result of the addition is not as it\'s supposed to be:

double _west = 9.482935         


        

Answer 1

The problem is that Double only has precision of 15 - 16 digits (and you seem to need more precision in your example) whereas Decimal has precision to 28 - 29. How are you converting between Double and Decimal?
