Hello, dear friends!

Please help me in my problem!

I described it in the attached video file.

In the input window, I have to enter the expression twice in order for the program to enter the number correctly. This is wrong.

The program must immediately, for the first time, enter the expression correctly.

Here is vidofile with comments

It doesn't depend on the protocol. I can send you a file .ggb to the mail. There are only 3 variables and everything is visible. Can you send me an email?

Post the File by Attach a file

It is always a good idea to add the file to posting....

Perhaps a rounding problem....

Try entering sqrt (3) twice.

The first time the approximate value is entered and b=false

the second time the exact value is entered and b=true

It is a rounding problem - give all decimal places (15).

I think input is cut to given decimal places.

numerical test for equality is always critical. try to test abs(a - in) < 10⁻³ for 3 decimal places
