number of decimal places

[shez]

Hi,

Is there any way to output a double value with different number of
decimal places (apart from using 'sprintf'). I looked up the reference
for C++ streams and found the 'setprecision' manipulator, but this sets
the number of digits before and after the decimal point. I can't seem
to find any manipulator for setting the number of digits after the
decimal point.

Thanks,

you would not need to be sorry, if you were so kind to post the answer you
have found - perhaps others are interested, too.

ps: ignoring, as you suggest, is not possible, because to do so, anybody
must read your original posting, plus your answer to it...

You can use the 'std::fixed' manipulator before setprecision, like
this:

std::cout << std::fixed << std::setprecision(2) << 1.2345678 <<
std::endl;

This should print to two decimal places. Thanks, -shez-

the above codes work for the newr compilers...if any of you are luking fr things that work with <xyz.h> files only...use the setf as follows


cout.setf(ios::fixed);
cout<<setprecision(4)<<number;


..//this prints exactly 4 digits after a decimal point
