y=0.049~0.51 Output error.

Please put more words into your post so we know what you are concerned about.

All the results are just as I would expect.

Keep in mind that when doing math on floating point numbers, the results may not match exactly what you'd expect if you were doing it on paper.  Not all decimal numbers can be represented exactly in the binary world that computers operate in.

How can there be an error if you don't even do any error handling.

What number do you enter, what do you get, and what do you expect to get instead?

As has already been said, floating point comparison are not very predictable. What are you trying to do?

Originally that post was in one of the Idea Exchanges.  I asked the moderator to move it out.

I'm not expecting anything fishy other than someone who isn't able to compose a reasonable message to explain their problem.

Lurkers are perfectly welcome here, though

The constant(x) compare with a control value(y) the result is x=y. But when use a number(x1) which came from the result of calculator's result, then do comparison with the control value(y). The result is x1<y.

Hi number,

yes, your results are expected and "by design" as has been said in message #2 and #3 one month ago…

Please set the formatting of ALL your controls, indicators and constants to show 17 decimal places - and you will see the reason behind your comparison results!
