The random number you generate might be different.

** Angles can be computed in degrees or radians. Examples show

angles in degrees. (See “

Choosing the Angle Units

” on page 5.)

Universal Power

;

Press

; to raise the displayed positive number to any power (for

example, 2

-5

or 2

(1/3)

).

Note: Because the reciprocal of an even number (such as, 1/2, 1/4, 1/6) is
a complex number, you can only raise a negative number to an integer
power or the reciprocal of an odd number.
