A class representing a 64-bit integer表示64位整数的类The internal representation of a long is the two given signed, 32-bit values.long的内部表示形式是两个给定的32位有符号值。We use 32-bit pieces because these are the size of integers on which Javascript performs bit-operations.我们使用32位片段，因为它们是Javascript执行位操作的整数大小。For operations like addition and multiplication, we split each number into 16 bit pieces, which can easily be multiplied within Javascript's floating-point representation without overflow or change in sign.对于加法和乘法等操作，我们将每个数字拆分为16位的部分，这些部分可以在Javascript的浮点表示中轻松地进行乘法运算，而不会溢出或改变符号。In the algorithms below, we frequently reduce the negative case to the positive case by negating the input(s) and then post-processing the result.在下面的算法中，我们经常通过对输入求反，然后对结果进行后处理，将否定情况减少为肯定情况。Note that we must ALWAYS check specially whether those values are MIN_VALUE (-2^63) because -MIN_VALUE == MIN_VALUE (since 2^63 cannot be represented as a positive number, it overflows back into a negative).请注意，我们必须始终特别检查这些值是否为MIN_VALUE（-2^63），因为-MIN_VALUE==MIN_WALUE（由于2^63不能表示为正数，它会溢出返回负数）。Not handling this case would often result in infinite recursion.不处理这种情况通常会导致无限递归。Common constant values ZERO, ONE, NEG_ONE, etc. are found as static properties on this class.常见常数值ZERO、ONE、NEG_ONE等都是此类的静态属性。
