Effect.Effect<number, never, never>Generates a random number between 0 (inclusive) and 1 (exclusive).
When to use
Use to generate a pseudo-random floating-point number in the standard
[0, 1) range.
Example (Generating a random number)
import { Effect, Random } from "effect"
const program = Effect.gen(function*() {
const randomDouble = yield* Random.next
console.log("Random double:", randomDouble)
})Random Number Generators
