As a simple exsample :

    protected void Page_Load(object sender, EventArgs e)
    {
        // Convert your float array to below 
        var list = new List<string>() { "'1.00'", "'2.00'", "'3.00'", "'4.00'" };
        Page.ClientScript.RegisterArrayDeclaration("arr ", string.Join("," , list.ToArray()));
        Page.ClientScript.RegisterStartupScript(this.GetType(), "excute", "<script language='javascript'>alert(arr);</script>");
    }

Here is an example by registering the values using clientscript:

On your code behind:

protected void Page_Load(object sender, EventArgs e)
{
  foreach(var f in myFloats)
     Page.ClientScript.RegisterArrayDeclaration("myFloats", f.ToString());
}

You see a more complete example here:

Hope it helps.
