浮动比较不匹配

Question

我有一个非常奇怪的错误,我无法弄清楚.

float distance = Utils.distance(this.spriteStartX, this.spriteStartY, this.getX(), this.getY());

Utils.log("D_Check: "+distance+" >= "+this.spriteDistance);

if(distance >= this.spriteDistance);
{
    Utils.log(distance+" is greater than "+this.spriteDistance);
}

在这段代码中,我确定了我的精灵来源与其当前位置之间的距离.(为简单起见,这是8.034246f).this.spriteDistance是7000.0f.

在我收到的调试器中:

D_Check: 8.034246 >= 7000.0
8.034246 is greater than 7000.0

显然这是非常错误的.我错过了一些非常简单的东西吗？

Answer 1

在if语句后删除分号.

if (distance >= this.spriteDistance)
{
    Utils.log(distance+" is greater than "+this.spriteDistance);
}

Answer 2

删除if语句末尾的分号.
