+ * 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.
