参数。随机值

返回：从原始随机字节的随机数

例子 #1 :

# Ruby code for Random.random_number() method
  
# loading library
require 'securerandom'
  
# declaring Random value
date_a = SecureRandom.random_number
  
# declaring Random value
date_b = SecureRandom.random_number
  
# random_number value
puts "Random random_number form : #{date_a}\n\n"
  
puts "Random random_number form : #{date_b}\n\n"

输出:

Random random_number form : 0.06094009368827358

Random random_number form : 0.23398922898567265

例子 #2 :

# Ruby code for Random.random_number() method
  
# loading library
require 'securerandom'
  
# declaring Random value
date_a = SecureRandom.random_number(10)
  
# declaring Random value
date_b = SecureRandom.random_number(200)
  
# random_number value
puts "Random random_number form : #{date_a}\n\n"
  
puts "Random random_number form : #{date_b}\n\n"

输出:

Random random_number form : 6

Random random_number form : 82
