The Nand command computes the bit-wise logical nand of the inputs returning in terms of a number. All bits that are unset in either input will be set in the output.

Nand takes one optional argument, bits=number that specifies the number of bits to be considered in the input. All bits past the specified number are truncated.

Use of this function requires that bits be set, either as an argument to Nand or globally via Settings.
