例子 #1 :

# Ruby code for DateTime.second_fraction() method
  
# loading library
require 'date'
  
# declaring DateTime value
date_a = DateTime.new(2019, 8, 10, 4, 10, 9)
  
# declaring DateTime value

# declaring DateTime value
date_c = DateTime.new(2019, 8, 10, 4, 10, 9, Rational(4, 24))
  
  
#  second_fraction method
puts "DateTime second_fraction form : #{date_a.second_fraction}\n\n"
  
puts "DateTime second_fraction form : #{date_b.second_fraction}\n\n"
  
puts "DateTime second_fraction form : #{date_c.second_fraction}\n\n"

输出:
