Inquiry about returned data of DHT11

Question

I'm using DHT22 for my measurement of temperature and humidity. As mentioned in its datasheet, data that returns from DHT22 is formatted in 40bit which consists of 8 bit integral RH, 8-bit decimal data, and the others for Temperature and checksum. However, its resolution is actually up to 1℃ or 1%RH, which means the decimal part should be zero for measured results. So, why it exists? Did I misunderstand something? Hope for your clarification. Thanks.

Answer 1

This datasheet says the resolution is 0.1% RH and 0.1°C. So the decimal part is needed to send that data.
