printf
Statements for Fancier PrintingFor more precise control over the output format than what is
normally provided by print
, use printf
.
printf
can be used to
specify the width to use for each item, as well as various
formatting choices for numbers (such as what output base to use, whether to
print an exponent, whether to print a sign, and how many digits to print
after the decimal point). This is done by supplying a string, called
the format string, that controls how and where to print the other
arguments.
