nl_tokens: Yes this will lose precision over 2^53 but that can t be helped when returning a single integer . We simply won t support packfiles over 8 petabytes . I m ok with that .
pl_tokens: function readUint64 ( buffer , offset ) { var hi = ( <mask> [ offset ] << 24 | buffer [ offset + 1 ] << 16 | buffer [ offset + 2 ] << 8 | buffer [ offset + 3 ] << 0 ) >>> 0 ; var lo = ( buffer [ offset + 4 ] << 24 | buffer [ offset + 5 ] << 16 | buffer [ offset + 6 ] << 8 | buffer [ offset + 7 ] << 0 ) >>> 0 ; return hi * 0x100000000 + lo ; }
