Why do my functions suddenly return values in ASCII code?

I have made simple functions in MatLab. For example:
function add(a,b)
fprintf('%d + %d = %d\n',a,b,a+b);
end
This used to work. However, using MatLab again after a while, this same function now returns values in ASCII code. Basically, given the inputs "4" and "5",
Before:
4 + 5 = 9
Now:
52 + 53 = 105
I don't remember doing anything that would cause this change. Simply typing "4 + 5" in the command window returns 9, but the problem arises when I make functions. Advice would be appreciated. (Version: R2022a)

It works, but the output seems to be in ASCII code instead of the original numbers I put it. i.e. if I input "4" and "5", it displays the input as "52" and "53". I know it "means" the same thing, but I just want to fix the formatting if that makes sense.

"but I just want to fix the formatting if that makes sense."
Changing the formatting cannot "fix" the fact that you call the function with incorrect inputs.

Ran in:
You accidentally used "command function equivalence". When you name a function without using () then the arguments you input are passed to the function as character vectors.
add 4 5
52 + 53 = 105
add(4, 5)
4 + 5 = 9
function add(a,b)
fprintf('%d + %d = %d\n',a,b,a+b);
end
