        @kamdroid Picture of basically what @iTap-Development said, put into behaviours (except I'm using 0 rather than 1)

          Just realized this won’t work if the input is already the number 0 though lol. You would still get the output of 1 (or 0).
          But another if would fix!

                @iTap-Development @Aidan-Oxley Thank you, this is a nice solution.

                edit: I just released my simple calculator, which is why I wanted to ask this question. https://www.hyperpad.com/projects/asudb1ye

                    EDIT: this does not work, use the other one somewhere above.

                      @aidan-oxley those first 2 ifs should be checking if it's zero, right? Because text+1 is the same as 0+1?

                        @jack8680 First it checks whether the value is the number 1 or not, if it is then it's done and it's a number. If it's not the number 1, then it adds 1 to it. If that result is 1, then it was text (since text will be treated as zero, so 0 + 1 = 1), if the result was not 1, then it is any number other than 1 (since 1 was already checked for at the start). I prefer adding 0 rather than 1 lol.

                            I thought the first if statements should check if it is 0, not 1, too.

                            If input was 0, 0+1 = 1, creating a false-positive to it being not a valid number.

                            If input was 1, and the if statements didn't exist, 1+1 = 2, this would say it is a valid number.

                              Ah ok, yeah the second one I made just to satisfy @iTap-Development's OCD wouldnt work, the first set of Ifs probably needed to stay as zero. Just use the one that adds zero lol.

                                  Whether you add 1 or 0 you still need all the ifs in both screen shots, right?
