i am programming a calculator for school and i have done everything
now he is asking me to enter number1-3 as decimals (EG. 1.1, 1.2, 1.3)
i cant figure out what to do.
can someone help?

you're using the wrong data type. use double instead of int.

Also, use input.nextDouble( ) instead of nextInt()

instead of grabbing number by number, why don't you have them input the full number:



Then parse the String using decimal.Parse(string)




If you want to go number by number, when don't you pull the input as an input.nextLine(), then check to see if it matches a "." string, else it's a number. Then just append all of it later
