I grew up in Northern Germany and attended the Christian-Albrechts-Universität in Kiel, a harbor town at the Baltic sea. I received a M.S. in computer science from Syracuse University, and a Ph.D. in mathematics from the University of Michigan in Ann Arbor. For four years, I was VP and CTO of an Internet startup that went from 3 people in a tiny office to a public company. I now teach computer science at San Jose State University and held visiting appointments at universities in Switzerland, Vietnam, and Macau. In my copious spare time I write books and articles on programming languages and computer science education.
printf("%10.2f", x);
cout << setw(10) << setprecision(2) << showpoint << x;
java.text.NumberFormat formatter = java.text.NumberFormat.getNumberInstance();
formatter.setMinimumFractionDigits(2);
formatter.setMaximumFractionDigits(2);
String s = formatter.format(x);
for (int i = s.length(); i < 10; i++) System.out.print(' ');
System.out.print(s);
System.out.printf("%10.2f", x);
printf("%10.2f", x)
(Thanks to Will Iverson for the update. He writes: “Note the lack of semi-colon. Improvement!”)
println(f"$x%10.2f")
(Thanks to Dominik Gruntz for the update, and to Paul Phillips for pointing out that this is the first version that is checked at compile time. Now that's progress.)
