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.
