代码 #1：inspect() 方法的示例

# Ruby code for inspect() method
  
# loading BigDecimal
require 'bigdecimal'
  
# declaring BigDecimal
a = 42.1**13
  
# declaring BigDecimal
b = -BigDecimal("10")
  
# declaring BigDecimal
c = -(22 ** 7.1) * 10
  
  
# a
puts "inspect value of a : #{a.inspect}\n\n"
  
# b
puts "inspect value of b : #{b.inspect}\n\n"
  
# c
puts "inspect value of c : #{c.inspect}\n\n"
     

输出 ：

inspect value of a : 1.3051704902006439e+21

inspect value of b : #

inspect value of c : -33978252067.813686

代码 #2：inspect() 方法的示例

# Ruby code for inspect() method
  
# loading BigDecimal
require 'bigdecimal'
  
# declaring BigDecimal
a = 12**12 - 27
  
# declaring BigDecimal
b = BigDecimal('10')-(22 ** 7.1) ** 10
  
# declaring BigDecimal
c = BigDecimal('-3')
  
# a
puts "inspect value of a : #{a.inspect}\n\n"
  
# b
puts "inspect value of b : #{b.inspect}\n\n"
  
# c
puts "inspect value of c : #{c.inspect}\n\n"

输出 ：
