Bitwise operations: Difference between revisions

In Babel, we prefix the logic operators with a 'c' to denote that they are C-style operations, that is, they are word-width operations, not arbitrary size operations. The following program combines the numbers 5 and 9 using the various bitwise operators and then displays the results.

<lang babel>({5 9}) ({cand} {cor} {cnor} {cxor} {cxnor} {shl} {shr} {ashr} {rol}) cart ! {give <- cp -> compose !} over ! {eval} over ! {;} each</lang>

{{Out}}

<pre>[val 0x1 ]

[val 0xd ]

[val 0xfffffff7 ]

[val 0xc ]

[val 0xfffffff3 ]

[val 0xa00 ]

[val 0x0 ]

[val 0x0 ]

[val 0xa00 ]</pre>

The cnot operator works on just one operand:

<lang babel>9 cnot ;</lang>

{{Out}}

<pre>[val 0xfffffff6 ]</pre>
