# declaring bigdecimal 
a = BigDecimal('12')*12

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]
