For Decimal values, lets say "25.2" code is as under.

if(thisObj.value.indexOf(".") >=0)
{
    if(fieldLength <= 4)
    {
        return true;
    }
    else
    {
        var str = thisObj.value;
        str = str.substring(0, str.length - 1);
        thisObj.value = str;
    }
}
else
{
    if(fieldLength <= 2)
    {
        return true;
    }
    else
    {
        var str = thisObj.value;
        str = str.substring(0, str.length - 1);
        thisObj.value = str;
    }
}
