From fixed point to floating point

Question

As input to my algorithm I get integer values which are scaled by 10. So if I get 10 it is actually 1, if I get 1 it is actually 0.1. I need to convert it to fractional representation for calculations and then convert back for output. I guess if I convert numbers to double there is a risk to loose some accuracy during convertations. What is the right way to solve this problem.

Answer 1

十进制类型为10个基数的计算提供了更高的精度（比浮点数高），这就是我要使用的精度。
