I am not 100% sure by your question.
If you want to convert time into number, multiply it by 24 and format it as general number. If you do, for example, 2.48 will become 2.80 as 48 minutes in term of general number is equal to .8 (48 minutes / 60 minutes).

You mean that you want to round up the number.
For example, what would be the output for times stamp 2:48 if you convert it to 'full number' as you are looking to do?
If you give the output that you are looking for, we can put a formula to do it.
