## linrand

linrand — Linear distribution random number generator (positive values only).

## Description

Linear distribution random number generator (positive values only). This is an x-class noise generator.

## Syntax

    ares linrand krange

    ires linrand krange

    kres linrand krange

## Performance

krange -- the range of the random numbers (0 - krange). Outputs only positive numbers.

For more detailed explanation of these distributions, see:

## Examples

Here is an example of the linrand opcode. It uses the file linrand.csd.
