例子 #1 :

# Ruby code for BigDecimal.split() method
  
# loading library
require 'bigdecimal'
  
# declaring bigdecimal
a = BigDecimal("10")
  
# declaring bigdecimal
b = -BigDecimal("10")
  
# declaring bigdecimal
c = -BigDecimal("11.43")
  
# split() method
puts "BigDecimal a split method : #{a.split()}\n\n"
  
puts "BigDecimal b split method : #{b.split()}\n\n"
  
puts "BigDecimal a split method : #{c.split()}\n\n"

输出:

BigDecimal a split method : [1, "1", 10, 2]

BigDecimal b split method : [-1, "1", 10, 2]

BigDecimal a split method : [-1, "1143", 10, 2]

例子 #2 :

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

输出:

BigDecimal a split method : [1, "144", 10, 3]

BigDecimal b split method : [-1, "20512110073058639999999999999999999999999999999999999999999999999999999999999999999999999999999", 10, 96]

BigDecimal a split method : [-1, "3", 10, 1]
