EQV

The EQV operator returns a value based on the equivalence of two conditions or values.

Syntax

result = firstValue EQV secondValue

Description

• Returns true (-1) when both values are the same (equivalent).
• Turns a bit on if both bits are the same, turns a bit off if both bits are different.

The results of the bitwise logical operations, where A and B are operands, and T and F indicate that a bit is set or not set:

Operands		Operations
A	B	NOT B	A AND B	A OR B	A XOR B	A EQV B	A IMP B
T	T	F	T	T	F	T	T
T	F	T	F	T	T	F	F
F	T	F	F	T	T	F	T
F	F	T	F	F	F	T	T

Relational Operations return negative one (-1, all bits set) and zero (0, no bits set) for true and false, respectively. This allows relational tests to be inverted and combined using the bitwise logical operations.
