Windows calculator does not accept it's own copied text as input

Ok, just tried the number you show and also got the same invalid error. Don't know why that is, perhaps it's the number scheme and they fact that you're essentially trying to input a number like that. Perhaps someone with more mathematical skills than I could explain. I did try the number without the "e-6" and was able to past successfully....

I think it has to be in Scientific mode. In Standard Mode, it will give that error, in Scientific mode it will accept it.

I already tried it in Scientific mode, I still get an "Invalid Input"...


I think trying to past the number with the "e" in it won't work by design. If you imputed the number manually, you don't have an "e" key to input the e.

This is where we could use a mathematician understanding calculators to help answer this one. That's not me

I didn't insert the e-6, just the rest of the number.

It possibly is a bug, the number is "too long"
the number is in scientific notation and you insert "e" using Exp:
paste the whole number then press: Exp +- 8
in the calculator

P.S. if you try a short number it works:

12e-8

Not so much a bug, but there is probably a limit on how many significant figures can be parsed when pasted.

Yes, too many numbers. I tried with 3 more numbers and got invalid input.

Of course, that number of significant figures is silly really anyway.

This reminds me of the old joke (sanitised here for propriety).

A guy has to choose between mathematician or engineer for a new job and sets them a task to decide.

He gets a bottle of vintage champagne and puts it at one end of room, and puts two guys at other end.

He asks how many steps it would take if you stepped half the distance on first step, quarter on next, eighth on next and so on halving each time. Whoever gets the right answer gets the job and the bubbly.

The mathematician says "it is a trick question, you can never reach it".

The engineer says 11. The potential boss replies "but the mathematician is correct - it is not possible".

The engineer says "true but after 11 steps, I will be so close it makes sfa difference"!

He gets the job and champers!
