Constant is not finite! That's illegal. constant:nan

近日，在开发的过程中在友盟统计上看到了我们的app出现了Constant is not finite! That's illegal. constant:nan的崩溃，定位之后只看到了这样的代码：
CGFloat percent =ceil(self.model.num1.floatValue / self.model.num2.floatValue)
self.percentViewWidthConstrait.constant = percent;
造成这个问题的原因就是这个除法的问题：我所发现的有两种可能（1）就是你的除数为0（2）除数或者被除数为null 这两种情况在你做除法的时候可能不会出现错误，但是当你设置constant的时候就会出现问题。
