Task

Write two equal-sized numerical arrays 'x' and 'y' to
a two-column text file named 'filename'.

The first column of the file contains values from an 'x'-array with a
given 'xprecision', the second -- values from 'y'-array with 'yprecision'.

For example, considering:

   x = {1, 2, 3, 1e11};
   y = {1, 1.4142135623730951, 1.7320508075688772, 316227.76601683791}; 
                                                          /* sqrt(x) */
   xprecision = 3;
   yprecision = 5;

The file should look like:

   1    1
   2    1.4142
   3    1.7321
   1e+011   3.1623e+005

This task is intended as a subtask for Measure relative performance of sorting algorithms implementations.

$xprecision = 3
$yprecision = 5 
$arr = foreach($i in 0..($x.count-1)) {
    [pscustomobject]@{x = "{0:g$xprecision}"  -f $x[$i]; y = "{0:g$yprecision}" -f $y[$i]}
} 
($arr | format-table -HideTableHeaders | Out-String).Trim() > filename.txt
