Julia's <tt>@sprintf</tt> macro provides string formatting that is similar to that of the c function of the same name. Though easy to use and efficient, <tt>@sprintf</tt> has limited flexibility, as its format specification must be a string literal, precluding its use in dynamic formatting. Greater flexibility is available via the <tt>Formatting</tt> package, which provides an implementation of Python's format specification mini-language. This solution demonstrates both of these techniques to provide the leading zero padded floating point format suggested in the task description ("%09.3f"). |
