How to Convert a Set of Strings to a Set of Floats in Ruby - Step by Step Examples

How to Convert a Set of Strings to a Set of Floats in Ruby ?

Answer

To convert a set of strings to a set of floats in Ruby, you can use the map method to convert each string into a float and then create a new set from the resulting array.


✐ Examples

1 Convert Set of Strings to Set of Floats Example 1

In this example,

  1. First, we create a set named string_set1 using the curly braces syntax, which contains the string values '1.1', '2.2', and '3.3'.
  2. Next, we use the map method on string_set1 to convert each string into a float using the to_f method.
  3. We convert the resulting array to a set using the to_set method, resulting in a set of floats named float_set1.
  4. Finally, we print the set of floats using puts.

Ruby Program

require 'set'

string_set1 = ['1.1', '2.2', '3.3']
float_set1 = string_set1.map(&:to_f).to_set
puts float_set1

Output

#<Set: {1.1, 2.2, 3.3}>

2 Convert Set of Strings to Set of Floats Example 2

In this example,

  1. We create a set named string_set2 using the curly braces syntax, which contains the string values '4.4', 'hello', '5.5', '6.6', and 'world'.
  2. We use the map method on string_set2 to convert each string into a float using the to_f method.
  3. We convert the resulting array to a set using the to_set method, resulting in a set of floats named float_set2.
  4. Finally, we print the set of floats using puts.

Ruby Program

require 'set'

string_set2 = ['4.4', 'hello', '5.5', '6.6', 'world']
float_set2 = string_set2.map(&:to_f).to_set
puts float_set2

Output

#<Set: {4.4, 0.0, 5.5, 6.6}>
