float val = 4.101814f;
float roundedVal = 0.01f * Mathf.Round(100.0f * val);

For efficiency you should use 100.0f but besides that absolutely right.

Oh for all Unityscript users that example is written in C# but the actual computation is the same:

// UnityScript
var val = 4.101814;
var roundedVal = 0.01 * Mathf.Round(100.0 * val);

If you want to display the float as string you should use a custom format string.

In your case

// C#
float val = 4.101814f;
Debuf.Log("The value is "+val.ToString("0.00"));
// prints: "The value is 4.10"

// UnityScript
var val = 4.101814f;
Debuf.Log("The value is "+val.ToString("0.00"));
// prints: "The value is 4.10"
