Bxor

Superseded / Deprecated

The feature described in this article has been superseded by a newer feature. This feature still works in PICO-8, but the new feature should be used instead. See the article's "Superseded by..." section for specific details.

bxor( first, second )

Calculates the bitwise-xor (exclusive or) of two numbers.

first

The first number.

second

The second number.

return-value

The bitwise-xor of first and second.

Superseded by ^^ operator

The ^^ operator added in 0.2.0 performs the same function as bxor() and is now the recommended way to do bitwise xor, as it uses fewer tokens, costs fewer cycles at runtime, and runs on the real host CPU much more efficiently. Simply replace bxor(a,b) with a^^b.

Examples

--     0x5 = 0101 binary
-- xor 0x9 = 1001 binary
-- -------
--     0xc = 1100 binary
print(bxor(0x5, 0x9))  -- 12 (0xc)

print(0x5 ^^ 0x9)      -- preferred method
