Method and
and()
Bitwise logical AND of the numerators
of the first two values on top of the stack and replaces them with the result.
Declaration
public void and()
Remarks
Manipulating denominators is possible by calling inv(Int32) beforehand.
Inversion of rational 0 values (0 / 1 => 1 / 0) results in NaN values which can be ignored for all bit-level operations.
