For example:

If this is a pause in the middle, it means 18 and 78, and those two 8 s mean 8, which means the same thing.

If it is a decimal point, it is 18.78, with the first eight representing 8 and the last eight representing 0.08.

The numerical difference is 8-0.08=7.02.

Extended data:

Take any number, write down the number of even numbers, the number of odd numbers and the sum of these two numbers in turn, and you will get a positive integer. For this new number, put its even and odd numbers and its sum into another positive integer, and so on, it will inevitably stay on the number 123.

For example, the given number is 1474 1029.

The first calculation result 448

The second calculation result 303

The third result is 123.
