    Infinity symbol on TI-84?

    Is there a way to enter infinity on the TI-84? I have not been able to find it, except entering a big number.

    Can you give an example of an expression that you would like to enter which would require a symbol for infinity?

    Example: normlcdf(lower,upper,u,s) in statiscs you may want to set the lower limit at -infinity. You can do this with the TI-nspire calculator.

    Actually I found that the infinity symbol is not included in the TI-84 but when the calculator inserts it automatically it uses "E99" or "-E99", which of course, you can enter yourself when needed.
