Can anybody tell me how to produce formatted output using streams instead of printf? Specifically, I am looking for a way to only show a desired number of significant digits when printing numbers. Example: foo = 5.0f; printf("%2.2f %2.5f\n", foo, foo); produces: 5.00 5.00000 When using a stream, you do this: foo = 5.0f; cout << foo << " " << foo << endl; The output is: 5.00000 5.00000 Unfortunately, I don't know how to trim the significant digits and I haven't found anything in texts or on the web. Can anybody answer this question? Thanks, jeeky [edited by - jeeky on July 15, 2002 10:03:21 AM] [edited by - jeeky on July 15, 2002 10:03:55 AM]

Check out the stream manipulators. Specifically, setprecision() should do what you want. For example:

cout << setprecision(5) << 0.123456789 << endl;

Your compiler help should list all the available manipulators.
