gas meter reading

I have a digital gas meter, The reading is 08483, these are the 5 digits before the decimal point.
There are only 4 boxes for me to enter my reading. The help section says I should be the 5 digits before the decimal point. Why is there not 5 boxes?

Hi, We will need to update the technical details we hold for you meter. If you could please email through to help@bulb.co.uk explaining the situation in the same way as above, then we can make this update. We would also want to check the serial number and other details, so a photo of the meter would be ideal if you could attach it to the email.
