Scientific Constants
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.
