In a complex calculation with multiple powers, an expression evaluates from the
beginning. Therefore, the expression “2^3^2” is interpreted as “(2
3
)
2
”. To evaluate the
expression “2
3
2
”, enter “2^(3^2)”.
• When the angle mode is set to Rad, it is possible to input π based on the equation
π = 180°(Deg).
To enter, press Ï π . It is possible to input “π” in the Deg mode. In that case,
calculations are based on “π = 3.14...” (degrees).
