RAND

Returns a random number between 0 and 1.

Syntax:

RAND()

This function produces a new random number each time Calc recalculates, greater than or equal to 0, and less than 1.
To force Calc to recalculate manually press Shift+Ctrl+F9.
To generate a random number which never recalculates, copy a cell containing =RAND(), and use Edit - Paste Special... (with Paste All and Formulas not selected and Numbers selected).

Example:

RAND()

returns a random number between 0 (inclusive) and 1 (exclusive).

RAND()*(b-a) + a

returns a random real number between a and b.
