数学计算 - 浮点数[重复](Math Calculation - float numbers [duplicate])

这个问题在这里已有答案:

我正在做以下事情

float years = (1/31536000) * 883102.00;

我得到年= 0000000

而实际答案是0.0.28

什么可能出错?


This question already has an answer here:

I am doing the following

float years = (1/31536000) * 883102.00;

and I get years = 0000000

while the actual answer is 0.0.28

Any suggestion on what might be going wrong ?

最满意答案

你应该这样做

float years = (1.0/31536000.0) * 883102.00;

要么

float years = (1.0/31536000) * 883102.00;

可能也会有效。 您的第一个数字被视为整数。


You should instead do

float years = (1.0/31536000.0) * 883102.00;

or

float years = (1.0/31536000) * 883102.00;

might work as well. Your very first number is treated as integer.
