This question already has an answer here: Is floating point math broken? 23 answers Because floating point arithmetic != real number arithmetic. An illustration of the difference due to imprecision is, for some floats a and b , (a+b)-b != a . This applies to any language using floats. Since floating point are binary numbers with finite precision, there's a finite amount of representa
这个问题在这里已经有了答案: 浮点数学是否被破坏? 23个答案 由于浮点运算!=实数运算。 对于一些花车a和b ,由于不精确造成的差异的例子是(a+b)-b != a 。 这适用于使用浮动的任何语言。 由于浮点数是有限精度的二进制数,因此有一定数量的可表示数,这会导致精度问题和这样的意外。 这里有另一个有趣的阅读:每个计算机科学家应该知道什么是浮点运算。 回到你的问题,基本上没有办法准确地表示二进制的34.99或0.
