红宝石 |随机 random_number()函数

Random#random_number() : random_number()是一个 Random 类方法，它检查从原始随机字节中返回一个随机数

Syntax: Random.random_number()

Parameter: Random values

Return: random number from raw random bytes

示例 #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

示例 #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
