RAND.NV

Mathematical

## Summary:

Generates a uniformly distributed random number in the range 0 (inclusive) to 1 (exclusive). In contrast to RAND, RAND.NV is a non-volatile function that is not recalculated at every input event.

RAND.NV()

## Returns:

Returns a real number in the range [0, 1).

## Arguments:

None.

• RAND.NV is a non-volatile function. Such functions are not recalculated at new input events and do not recalculate when selecting Data ▸ Calculate ▸ Recalculate or pressing F9, except when the cell containing the function is selected. Non-volatile functions are recalculated when opening the file.
• Use the RAND function for a volatile equivalent that satisfies ODF 1.2 and is compatible with Microsoft Excel.
• To generate random numbers that never recalculate, either:
• Copy cells containing `=RAND.NV()`, and use Edit ▸ Paste Special (with All and Formulas deselected and Numbers selected).
• Use Sheet ▸ Fill Cells ▸ Fill Random Number to fill a selected cell range with random numbers, generated in accordance with the flexible settings available through the Random Number Generator dialog.
• To generate numbers in a range other than [0, 1), either:
• Scale the value returned by RAND.NV to a new range using a formula of the form `=(RAND.NV()*(b-a))+a` to generate a number in the range [a, b]. For example, the formula `=(RAND.NV()*20)-10` would generate random numbers in the range [-10, 10).
• Use the RANDBETWEEN function or its non-volatile equivalent RANDBETWEEN.NV.

## Examples:

Formula Description Returns
=RAND.NV() Generates a random number r in the range 0 ≤ r < 1. The resulting value will not change whenever Calc recalculates. 0.80206289793007
