Can you ever use a calculator to determine if a number is rational or irrational?
The answer to your question begins with a question to you. How do you know what number you are interested in ? How is it specified ? If the number is written down as a decimal, it must have a finite number of digits. This would make it a rational number. If it is written down as a fraction, that also is rational. If the number is specified as a procedure, that may or may not be rational. You make the determination using your head for logical thought - something calculators can't do. So, the short answer to your question is : no, except for a few very special cases, most of which are susceptible to logical analysis anyway.
