Unless otherwise noted, the functions in this section can be used in any of the calculator’s 
calculation modes, except for the BASE Mode. 

• When performing a calculation that includes a built-in scientifi c function, it may take 

some time before the calculation result appears. Do not perform any key operation on the 
calculator until the calculation result appears. 

• To interrupt and on-going calculation operation, press  

A.

• Text that represents a function’s argument is enclosed in braces ({ }).  Arguments are 

normally {value} or {expression}. 

• When braces ({ }) are enclosed within parentheses, it means that input of everything 

inside the parentheses is mandatory.
