Squareroot gives strange result
Hi

I am relatively new to the Prime (about 6 months) but all in all i love this calculator.
But sometimes i discover some unexpected behaviours.
Today i found a new one which costs me many hours to get behind.

Please take a looks at the attached picture.
It looks (for me) that there is a bug in the way the prime interprets exponents?

The first result is the correct and the expected one.
But i thought that i can save some time by using the EEX key to define the exponent of a number.
Looks like this does not work if used inside a sqrt.

If someone know more about this behaviour i would be very happy to get more informations about it.

Thank you.

Do you have engineering mode selected? It looks like that to me.

Choose a different format, then, and your answer will be what you expect.

I have changed back to standard number format.
Still the same behaviour.

Note that I didn't give you any hint.
Just a claim.
You found the correction all by yourself.
