Float Type

Float Type

Float represents floating-point (decimal) numbers in Ruby, following standard IEEE 754 double-precision behavior, including the usual floating-point rounding quirks. Dividing two integers with / gives integer division, so at least one operand must be a Float to get a fractional result. to_f converts a value to a float explicitly.

Note: Divide with 10.0 / 3 (or call .to_f on an operand) to force a fractional result instead of integer division.

Example: Float Type

price = 19.99
puts price.class
puts price * 2

puts 10 / 3          # integer division
puts 10.0 / 3         # float division
puts 10.to_f / 3
