双精度值 [英] double value precision

问题描述

大家好，我正在使用Visual Studio 2008并操纵双重加法.

Hello All, I am using visual studio 2008 and maniplulating double addition.

double a = 1.5000010 ;
double b = 0.0000090;
double c = a+b;

我在这里期望的输出是1.5000100，但实际输出为1.5000099999999998.

我不必考虑超过7个小数点，因此输出结果为1.5000099.

如何将其转换或存储为我喜欢的格式?表示1.5000100.

是否有任何内置方法或win32 API可以做到这一点?

预先感谢.

The output I am expecting here is 1.5000100 but the actual output comes as 1.5000099999999998.

I dont have to consider more than 7 fractional points so the output comes like 1.5000099.

How do i convert or store this in to the format which i like? that means 1.5000100.

Is there any built-in method or win32 API available to do this?

Thanks in advance.
