Scientific Constants
(fx-570MS/991MS only)
Your calculator comes with 40 built-in scientific constants that can
be used in any mode besides BASE. 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
h and
then input the two-digit number that corresponds to the constant
you want.
To input the scientific constant C
