(rA' dE *u*n) *n.*

a unit of arc for which the arc length is equal to the radius of the circle. A radian is approximately equal to 57.296 degrees. SAS trigonometric functions use angles measured in radians.

Abbr. **rad**.

(rA' di O boks) *n.*

a set of buttons, each representing a different option identified in an associated label, allowing a user to select one option from a set of option by selecting the button associated with that option. The selection of one button in a radio box causes all other buttons in the radio box to be deselected.

(rA' di O but' n) *n.*

one of the buttons in a radio box.

(ram') [random access memory] *n.*

ordinary memory that can be used by a program to contain the objects it creates and uses while it runs.

*n.*

1. a number selected randomly.

2. also, **pseudo-random number**.
a number generated by a mathematical
process (a **random number generator**)
that simulates the essential qualities of a random number.
