📝 Usage

Basic

import rand from 'twistrand'

const mtDefault = rand(/* Use `Date.now()` in default */)

const mt1 = rand(12345)
const mt2 = rand(12345)

mt1.random() === mt2.random() // true
mt1.randomInt(0, 100) === mt2.randomInt(0, 100) // true
mt1.randomFloat(0.0, 100.0) === mt2.randomFloat(0.0, 100.0) // true

const mt = rand(12345)
const v1 = mt.random()
const v2 = mt.random()

v1 !== v2 // true

Output

const mt = rand()

• x = mt.random(): x ∈ [0, 1)
• x = mt.randomFloat(0, 100): x ∈ [0, 100)
• x = mt.randomInt(0, 100): x ∈ [0, 100] x ∈ Z
