API

table require"lrand"

The module table containing the API.

string lrand.version

The version string.

Creates a new lrand_state, optionally seeded with a lua integer.

lrand_state lrand.clone(state)

Can also be called from the state state:clone().

Clones the state into a new lrand_state.

lrand_state lrand.seed(state[, seed])

Can also be called from the state state:seed([seed]).

Reseeds the state with an optional lua integer.

integer lrand.randu64(state)

Can also be called from the state state:randu64().

Consumes a random unsigned int64 from the state which is returned as a lua integer.

(raw range: [0, 2^64-1]) (range in lua: [math.mininteger, math.maxinteger])

integer lrand.randi64(state)

Can also be called from the state state:randi64().

Consumes a random int64 from the state which is returned as a lua integer.

(raw range: [0, 2^63-1]) (range in lua: [0, math.maxinteger] (may overflow in 'small lua'))

number lrand.randd(state)

Can also be called from the state state:randd().

Consumes a random real number from the state which is returned as a lua number.
