Keys and Description

>()

Logic operator

Turns the calculator off.

{Permutations of n items taken r at a time. Returns n!⎟(n – r)!.

Activates or cancels (toggles) Program–entry mode.

Pause.

Halts program execution briefly to display x, variable, or equation, then resumes. (Used only in programs.)

ÕÕ() Returns the correlation coefficient between the x– and y–values:

∑(xi − x)(yi − y)

∑(xi − x)2 ⋅ (yi − y)2

8() Changes the display of complex numbers.9()Selects Radians angular mode.Degrees to radians. Returns (2π/360) x.8(6)Selects the comma as the radix mark (decimal point).8()Selects the period as the radix mark (decimal point).Executes the RANDOM function. Returns a random number in the range 0 through 1.variable Recall.Copies variable into the X–register.
