Scalar. Returns a value with all bits set to 0, except a specified range of bits.
bitmasklong ( first, last )
| first | The first bit to set, starting from 0 as the least-significant bit. |
| last | The last bit to set, starting from 0 as the least-significant bit. |
Both arguments must be integers, and the function returns a long.
bitmasklong (33, 35) returns 60129542144 or 111000000000000000000000000000000000 in binary.
