Number Fomatting

[utab]

Hi there,

I have double values x, y and z like the ones below

1.19809 0.465934 0.0197982

so I want to limit the width of these numbers as 8 while preserving the
maximum available precision. Does the standard library have something
to do with these kinds of operations?

For example for this particular problem, the last number is 9
characters wide and I would like to present that as 0.019798.

Thanks in advance.

See std::setiosflags() and setprecision()

Have a look at the standard manipulators setw(int) and setprecision(int)

Sorry a typo, I meant setiosflags() (without the std) and
setprecision()
