|

* Constructs a 64-bit two's-complement integer, given its low and high 32-bit
|
||||
* 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, 32-bit values.
|
||||
* We use 32-bit pieces because these are the size of integers on which
|
||||
* Javascript performs bit-operations. 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.
|
||||
*
|
||||
* 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.
|
||||
* 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.
