Using printf Statements for Fancier Printing

If you want more precise control over the output format than print gives you, use printf. With printf you can specify the width to use for each item, and you can specify various stylistic choices for numbers (such as what radix to use, whether to print an exponent, whether to print a sign, and how many digits to print after the decimal point). You do this by specifying a string, called the format string, which controls how and where to print the other arguments.
