Defines a Long class for representing a 64bit two’scomplement integer value, which faithfully simulates the behavior of a Java “Long”. This implementation is derived from LongLib in GWT.
 class Long()¶
Arguments:
 low (number) – the low (signed) 32 bits of the Long.
 high (number) – the high (signed) 32 bits of the Long.
Constructs a 64bit two’scomplement integer, given its low and high 32bit values as signed integers. See the from* functions below for more convenient ways of constructing Longs.
The internal representation of a Long is the two given signed, 32bit values. We use 32bit pieces because these are the size of integers on which Javascript performs bitoperations. For operations like addition and multiplication, we split each number into 16bit pieces, which can easily be multiplied within Javascript’s floatingpoint representation without overflow or change in sign.
In the algorithms below, we frequently reduce the negative case to the positive case by negating the input(s) and then postprocessing the result. 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). Not handling this case would often result in infinite recursion.
