linrand — Linear distribution random number generator (positive values only).
Linear distribution random number generator (positive values only). This is an x-class noise generator.
krange -- the range of the random numbers (0 - krange). Outputs only positive numbers.
For more detailed explanation of these distributions, see:

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