Looking for BOOLEAN ALGEBRA functions (specifically XOR)
An XOR could operate on any number of binary bits.
An odd parity checker would XOR all given bits,
thus checking for an odd number of bits in a word:
=MOD(1+MOD(HEX2BIN("AE")-1,9),2)
I vote for Harlan's formulas, having lifted them from
his post dated Jun 16, 2003.
