Problem Statement

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: The file should look like: This task is intended as a subtask for Measure relative performance of sorting algorithms implementations.

Let's start with the solution:

data _null_;
input x y;
file "output.txt";
put x 12.3 " " y 12.5;
