Scientific Function Calculations

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

Scientific Function Calculation Precautions

•When performing a calculation that includes a built-in scientific 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.

Interpreting Scientific Function Syntax

•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.
