No scientific notation?

[Ville Ahonen]

I'm a total beginner at C++ so please bear with me.. When i write

cout << stddev * stddev << endl;

I get the output "4.49513e-05". How can I rephrase the above so that I
would instead get the output "0.000049513"?

Thanks alot,

Ville

cout << fixed << stddev*stddev << endl;

cout << fixed << stddev*stddev << endl;

To elaborate:

You can also use 'setprecision(n)' to control the
number of digits after the decimal point.

'std::fixed' is declared by <ios>, and
'std::setprecision()' is declared by <iomanip>
