Perl Weekly Challenge 386: Base Conversion and Repeating Decimal Comparison

The 386th Perl Weekly Challenge presents two mathematical programming tasks for participants to solve. The first task requires writing a function that converts a string representation of a number in any given base back into a standard integer, essentially reversing the previous week's challenge. The second task asks programmers to determine whether two non-negative rational numbers expressed as repeating decimals are equal. The recommended approach for the second task involves converting each repeating decimal into a standard fraction using algebraic manipulation, then comparing the two fractions. Perl's built-in bigrat module is suggested as a convenient tool for handling rational number arithmetic with automatic fraction reduction.
