Could someone please tell me how to format data using cout?
For example, when using printf if I wanted to print out a floating point number to 2 decimal places I would do:
Is it possible to do this using cout. The only way I have found is to use sprintf, and give cout the pointer. But surely there is a simpler way.
Thanks in advance.
cout << 2.3456764 << endl;
should out : 2.34.
keep in mind precision specifies the number of significant digits, not the number of decimal places.
