Ans column of the List Screen when the value input for the corresponding 
sample data is outside the allowable range.

Your calculator comes with 40 built-in scientific constants that can be used in 
any mode besides BASE-N. Each scientific constant is displayed as a unique 
symbol (such as 

π), which can be used inside of calculations. 

To input a scientific constant into a calculation, press 

17(CONST) and 

then input the two-digit number that corresponds to the constant you want.
