I need to convert fixnums to strings. My solution is:
arr.map {|a| a.to_s}
Is there a better way?

In Ruby, we can convert an array into a string using the join method. The join method takes the array and a separator as the arguments. It then separates the elements in the array using the specified separator value.
The at() method of an array in Ruby is used to access elements of an array. It accepts an integer value and returns the element.
The array as a parameter to the puts or print method is the simplest way to print the contents of the array. Each element is printed on a separate line. Using the inspect method, the output is more readable. The line prints the string representation of the array to the terminal.
The user can convert strings to ints or floats by using the methods to_i and to_f , respectively. Other types to string: The user can convert other datatypes to string by using the to_s method.
arr.map(&:to_s)
This uses a spiffy new feature in Ruby >= 1.8.7, the "symbol to proc" shortcut, and is equivalent to the code in your question.
