Formatted numeric output: Difference between revisions

=={{header|Wren}}==

Wren doesn't have any kind of numeric formatting built in so we need to write a function to complete this task.

<lang ecmascript>var rzset = Fn.new { |m, n|

var s = "%(n)"

var c = s.count

return (m > c) ? "0" * (m - c) + s : s

}

var n = 7.125

System.print(rzset.call(9, n))</lang>

{{out}}

<pre>

00007.125
