|

|
|
* 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
