Big integers

Package: BIGINT_PACKAGE. Registered by createEngine(); for a slimmer engine, register it explicitly (see choosing packages).

An ordinary number loses precision once it grows past a certain size, and bitwise work is limited to a 32-bit range. A big integer sidesteps both: suffix an integer with n and it is held as a whole number of any size, exactly.

Suffix an integer with n to keep full precision beyond the safe range for ordinary numbers, and for bitwise work that overflows the 32-bit range and needs ordinary integer arithmetic instead.
