Sequences have a start point, an end point, and a way to produce successive values in the sequence. Ruby creates these sequences using the ''..'' and '''' range operators. The two-dot form creates an inclusive range Ruby has methods for working with different encoding systems. For example: "abc".encoding.name # "UTF-8" There are a few special scenarios where the current encoding (encoding.name) doesn’t match the actual encoding of the string.

You can use the Integer method to convert a String to an Integer: Integer ("123") # => 123 Integer ("0xFF") # => 255 Integer ("0b100") # => 4 Integer ("0555") # => 365 You can also pass a base parameter to the Integer method to convert numbers from a certain base Integer ('10', 5) # => 5 Integer ('74', 8) # => 60 Integer ('NUM', 36) # => 30910

In any case, strings should be strictly conformed to numeric representation. This behavior is different from that of String#to_i. Returns the result of interpreting leading characters in str as an integer base base (between 2 and 36).

We use to_i to convert a float into Fixnum ( or integer ). Also, we can use to_f to do the conversion to Float. See the following example to understand this. See full list on blog.udemy.com Perhaps I'm just nitpicking semantics and most people just see (Ruby on) Rails and Ruby as synonymous in cases like this. – Chinoto Vokro Jul 27 '16 at 20:32 Is there a way to ensure all math in a certain block is performed on floats (and where not float, coerced to float) without having to .to_f everything? – stevec Oct 2 '20 at 13:25 Ruby Basic Literals.
