javascript如何计算第一个数学运算？
最佳答案
根据 spec
0/0 输出 NaN 因为
Division of a zero by a zero results in NaN; division of zero by any other finite value results in zero, with the sign determined by the rule already stated above.
和1/0输出无穷大因为
Division of a nonzero finite value by a zero results in a signed infinity. The sign is determined by the rule already stated above.
