- Definition:
This is a "meta"-generator which combines a number of PRNG into one single generator by adding the respective numbers modulo 1.

- Name (as given to
`prng_new`

):`"c(generator1,generator2, ...)"`

.Up to

`PRNG_MAX_COMPOUNDS`

generators are permitted.`generatorX`may be any valid generator definition, including a compound generator. - Properties:
- Period length: Least common multiple of the period length's of the component generators.
- Generally speaking, most properties of PRNG are preserved if combining generators of the same type.
`prng_is_congruential`

is`FALSE`

.`prng_can_seed`

is`TRUE`

.- The parameters of
`prng_seed`

is used to seed all seedable component generators. `prng_can_fast_sub`

and`prng_can_fast_con`

depend on the underlying generators.
