Returns the <code>0.0..1.0</code> strength of a named <a href="input-bind.html">action</a> — <code>1.0</code> when any bound key is held, <code>0</code> otherwise for keys (digital), and the analog magnitude when a gamepad feeds the action. Lets analog and digital sources share one read.

```ludic
program Demo {
  entry {
    Input.bind("gas", 'w')
    Input.press('w')
    Input.poll()
    print(Math.round(Input.strength("gas")))
  }
}
