*1 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).
