Excuse me in case this questin is silly, but from what I understand, the letter A is assigned a smaller float value than the letter B, because B comes after A in the alphabet. What about symbols such as # What values are assigned to them? Is there a table somewhere where I can read off the numerical values taken by each symbol?
I tried finding some table of values online
I think the table you are looking for is an ASCII table, which is a standard conversion from characters to numbers.
For example, "A" is 65, "B" is 66, etc.
A "#" is 35.
