9. FUNCTION CALCULATIONS
Scientific function keys can be utilized as subroutines of
four basic calculations (including parenthesis
calculations).
■
This calculator computes as
π
= 3.141592654 and
e
= 2.718281828
■
In some scientific functions, the display disappears
momentarily while complicated formulas are being
processed. So do not enter numerals or press the
function key until the previous answer is displayed.
■
You cannot specify the unit of angular measurement
(degrees, radians, grads) or the display format (FIX,
SCI) while the calculator is performing BASE-N
calculation. Such specifications can only be made if
you first exit the BASE-N mode by pressing the
key.
■
For each input range of the scientific functions, see
page 39.
9-1) Sexagesimal
↔
Decimal conversion
The
key converts the sexagesimal figure (degree,
minute and second) to decimal notation. Operation of
converts the decimal notation to the
sexagesimal notation.
