* 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.
