What means cout.precision (4)?

[George2]

Hi, everyone!

What means cout.precision (4)? Who can give me
a sample to show the usage?


Thanks in advance,
George

it sets the precision of floating point numbers same as the "%.4f" formatter

example

cout.pecision(4);
cout << 445.26382011334;

will output
445.2638
