Chapter 8 Numeric Functions 189
RAND
The RAND function returns a random number that is greater than or equal to 0 and
less than 1.
RAND()
Usage Notes
The RAND function does not have any arguments. However, you must include the Â
parentheses: =RAND().
Any time you change a value in the table, a new random number greater than or Â
equal to 0 and less than 1 is generated.
Example
=RAND() returns, for example, 0.217538648284972, 0.6137690856, 0.0296026556752622, and
0.4684193600 for four recalculations.
