Non-programmers should note that, as in many other programming
languages, expressions involving only integers (whether constants
without a `tt(.)', variables containing such constants as strings, or
variables declared to be integers) are by default evaluated using
integer arithmetic, which is not how an ordinary desk calculator
operates. To force floating point operation, pass the option tt(-f);
