ANDV

ANDV is a CAOS command for a bitwise operation.

Usage
Syntax: ANDV var (int variable) mask (int)

This performs a bitwise AND on var. Bitwise AND matches up the bits of var and mask which both contain 1, and produces a new sequence of bits which contains 1s in these positions. In C, ANDV would be written.

The arguments must be integers (though the second will be cast if a float). They will be treated as signed 32-bit using two's complement.

Examples
Here is a simple AND operation: SETV va00 24 * 24 = %11000 ANDV va00 14 * 14 = %01110 OUTV va00 8        * 8  = %01000

This implements  using ANDV and ORRV: * va00 = A; va01 = B SETV va02 va00 NOTV va02 * va02 = ~A SETV va03 va01 NOTV va03 * va03 = ~B ANDV va00 va03          * va00 = A & ~B ANDV va02 va01          * va03 = ~A & B ORRV va00 va02           * va00 = (A & ~B) | (~A & B) As an example, performing the above with va00 = 5 (%0101) and va01 = 3 (%0011) yields va00 = 6 (%0110).
