# Fill Random Numbers

Populate a cell range with automatically generated pseudo random numbers with the selected distribution function and its parameters.

To access this command...

Choose Sheet - Fill Cells - Random Number

## Data

### Cell range

Define the range of cells to fill with random numbers. If you have previously selected a range, it will be displayed here.

## Random number generator

### Distribution

The distribution function for the random number generator.

Valid distributions function and their parameters are

Distribution | Parameters
Uniform | Minimum: The minimum value of the sample. Maximum: The maximum value of the sample.
Uniform Integer | Minimum: The minimum value of the sample. Maximum: The maximum value of the sample.
Normal | Mean: The mean of the Normal distribution. Standard Deviation: The standard deviation of the Normal distribution. The mean and standard deviation of the numbers generated may not equal the Mean and Standard Deviation inserted in the dialog.
Cauchy | Median: the median of the data or location parameter. Sigma: the scale parameter. The median and sigma of the generated numbers may not equal the data inserted in the dialog.
Bernoulli | SP is the probability of success on each trial.
Binomial | SP is the probability of success on each trial. Number of trials: the number of trials of the experiment.
Chi Squared | Nu Value: a positive integer that specifies the number of degrees of freedom.
Geometric | SP is the probability of success on each trial.
Negative Binomial | SP is the probability of success on each trial. Number of trials: the number of trials of the experiment.

## Options

### Enable custom seed

Set the initial value of the random number generator to a known value Seed.

### Speed

Value set to initiate the random number generator algorithm. It is used to initialize (seed) the random number generator in order to reproduce the same sequence of pseudorandom numbers. Specify a positive integer number (1, 2, ...) to produce a specific sequence, or leave the field blank if you don't need this particular feature.

### Enable rounding

Truncate the number to a given number of Decimal Places.

### Decimal places

Number of decimal places of the numbers generated.
