Writing analog values doesn't work

[MH-EQ]

The problem is caused by this method:

private static Encodable encodeFloat(Type type){
    if(type instanceof DecimalType){
        return new Real(((PercentType)type).floatValue());
    }
    throw new IllegalArgumentException("Cannot convert openHAB type " + type + " to integer");
}

The cast is wrong. As the if has proven, the value is of class DecimalType, not of class PercentType. Casting to DecimalType makes writing work again.
