var/a,b


Is there a way that when a number is bigger than 65535 without that E thing?

Yeah. The "E" thing is similar to scientific notation, perhaps another form of it. Anyway, when outputting the answer, just use num2text.

By the way, you shouldn't use A and B as variables for public use. Maybe just verb variables, so it reduces bugs when playing with more than one person.

Then you may try and specifiy what you want from each input as well, like listed.
mob/verb
    Addition()
        var/a=input("Pick a number to add.","Addition")as num 
        var/b=input("Pick another number to add to the previous.","Addition")as num 
        src<<"[num2text(a+b)]"
    Multiplication()
        var/a=input("Choose a number to multiply.","Multiplication")as num 
        var/b=input("Pick another number to multiply with the previous.","Multiplication")as num 
        src<<"[num2text(a*b)]"
    Subtraction()
        var/a=input("Pick a number to be subtracted from.","Subtraction")as num 
        var/b=input("Pick a number to subtract from the previous.","Subtraction")as num 
        src<<"[num2text(a-b)]"
    Division()
        a =input("Pick the number to be divided.","Divison")as num 
        b =input("Pick the number to divide the previous by.","Division")as num 
        src<<"[num2text(a/b)]"


Alright, now, let's say you only want to display nine digits before getting into scientific notation. You would use num2text(mathhere,9)

E is the exact same thing as scientific notation. I do believe the E stands for "exponential notation", meaning "times ten to the Nth power where N is the number after E". The terms exponential notation and scientific notation mean almost exactly the same thing. The only difference is that scientific notation always multiplies by the base of the number system in use.

1E7 = 1*10**7

All scientific notation is, is cutting off insignificant digits by multiplying the number by base to the number of digits desired.

Many people, even scientists - for whom the notation is named, obviously - say exponential notation instead of scientific notation and mean the same thing.

Sorry, I guess I went on there more than needed. Bottom line, the E means it is in scientific notation, to be multiplied by 10**N.

how can i complety avoid scientific notaion, how can i have a answer with 30 digits or less or more

other problem
    Power()
        var/a =input("What number.","Power")as num
        var/b =input("To what power?","Power")as num
        src<<"[num2text(a**b)]"

say i put the number 100 and bring it to the 100 why doe's it output 1.#INF

Why don't you try multiplying a hundred times one hundred, a hundred times? See how far you get. It may say that after BYOND wants to stop counting for whatever reason, but I do know that there is a limit to a number before it reaches 1#.INF.

and how do i get rid of scientific notation so i can have unlimited digits.

1.#INF means that BYOND has run out of numbers. There is a limit to the amount of numbers you can count with only a handful of bytes. =)

As for getting rid of scientific notation, look up num2text() in the reference. See that optional second argument? Set it to something suitably high, like 1000000.

optional argumnet as in the second argumnet I presume.
num2text(2000000,99)
This means that scientific notation isnt envoked until
after the first 99 numbers.
Hope that helped.
