Pop two integers, floats, or strings, compute whether they are ordered from smaller to larger and push the Boolean result back on the stack.

It is possible to test whether two values are Greater Than or Equal using the Logical Not operator on the result of Less Than. The Greater Than (typed) operator is used to support the other two comparison operators (thus eliminating the need to swap the top of the stack as in version 4.)
