m b. Inverses Implemented |
initial writing: 2007-10-15 |
Inverses of the following cases of the bitwise boolean functions m b. have been implemented. x and y are integer atoms.
| m | Verb(s) | Inverse | ||||
| 19 | left | (m b.)&y | self-inverse | |||
| 21 | right | x&(m b.) | self-inverse | |||
| 22 | not equal | x&(m b.) (m b.)&y | self-inverse | |||
| 25 | equal | x&(m b.) (m b.)&y | self-inverse | |||
| 26 | not right | x&(m b.) | self-inverse | |||
| 28 | not left | (m b.)&y | self-inverse | |||
| 32 | rotate | x&(m b.) | (-x)&(m b.) | |||
| 33 | shift | x&(m b.) | (-x)&(m b.) | |||
| 34 | signed shift | x&(m b.) | (-x)&(m b.) |
