public static method Clamp01(value: float): float;
public static float Clamp01(float value);

## Description

Clamps value between 0 and 1 and returns value.

If the value is negative then zero is returned. If value is greater than one then one is returned.

// Set the position of the transform to be that of the time
// but never less than 0 or more than 1
function Update () {
transform.position = Vector3(Mathf.Clamp01(Time.time), 0, 0);
}

// Print a random number every second. This number is chosen over a // range from startValue to endValue. The random number is clamped // to between zero and one by Clamp01().

public class ExampleScript : MonoBehaviour { public float startValue = -0.5f; public float endValue = 1.5f;

private float timeCount = 0.0f;

void FixedUpdate() { timeCount += Time.deltaTime;

if (timeCount > 1.0f) { float result = Random.value; result = result * (endValue - startValue); result = result + startValue;

float clampValue = Mathf.Clamp01(result);

Debug.Log("value: " + result.ToString("F3") + " result: " + clampValue.ToString("F3"));

timeCount = 0.0f; } } }
