Question

If you have a string ten, is it possible to convert it to an integer 10 in Ruby? (maybe in rails?)

I value the developers at tryruby.org, and in their tutorial here, it specifically says “to_i converts things to integers (numbers.)” I am wondering why they didn’t say “to_i converts STRINGS to integers (numbers.)”

What variable types can be converted from their type to an integer?

Answer 1

Check out this gem for handling word to number conversions.

From the readme:

require 'numbers_in_words'
require 'numbers_in_words/duck_punch'

112.in_words
#=> one hundred and twelve
"Seventy million, five-hundred and fifty six thousand point eight nine three".in_numbers
#=> 70556000.893
