## Function name:

SATUNNAISLUKU.PYSYVÄ

Mathematical

## Summary:

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

## Syntax:

SATUNNAISLUKU.PYSYVÄ()

## Returns:

Tuottaa kokonaisluvun väliltä [0,1).

## Arguments:

None.

• SATUNNAISLUKU.PYSYVÄ 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 SATUNNAISLUKU 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 =SATUNNAISLUKU.PYSYVÄ(), 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 SATUNNAISLUKU.PYSYVÄ to a new range using a formula of the form =(SATUNNAISLUKU.PYSYVÄ()*(b-a))+a to generate a number in the range [a, b]. For example, the formula =(SATUNNAISLUKU.PYSYVÄ()*20)-10 would generate random numbers in the range [-10, 10).
• Use the SATUNNAISLUKU.VÄLILTÄ function or its non-volatile equivalent SATUNNAISLUKU.VÄLILTÄ.PYSYVÄ.

## Examples:

Formula Description Returns
=SATUNNAISLUKU.PYSYVÄ() Generates a random number r in the range 0 ≤ r < 1. The resulting value will not change whenever Calc recalculates. 0,80206289793007
