How to convert number to real number?

Dear all,

My code calculates the MSE as a result

perf =

    1.1970e-011

How I convert this type of number to real or some "normal" number?

Thank you for your answers.

What is it meant by real/normal number ? Isn't this answer a real number?

[Veronika]

I don´t know, I just want to number without e.

[Veronika]

Ok, I agree.

[Giorgos Papakonstantinou]

   sprintf('%.15f', 1.1970e-011)

This is a real number. Just small enough that scientific notation was employed to display it, to avoid a plethora of zeros. There is NOTHING abnormal about it.

1.1970e-011 == 1.1970 * 10^(-11)

For the second time recently, I find myself amazed that kids no longer learn what scientific notation is in school anymore.

It begs the question: if 1.1970e-011 written as a "normal" number would be 0.00000000001197, how should they then write 7e-303 ?

I would love to read an astronomy report written by that class!
