When to use

Use to parse numeric text without throwing on invalid input.

import { Number } from "effect"

Number.parse("42") // Option.some(42)
Number.parse("3.14") // Option.some(3.14)
Number.parse("NaN") // Option.some(NaN)
Number.parse("Infinity") // Option.some(Infinity)
Number.parse("-Infinity") // Option.some(-Infinity)
Number.parse("not a number") // Option.none()
