红宝石 | BigDecimal split()函数

BigDecimal#split() : split()是一个 BigDecimal 类方法，它将 BigDecimal 数拆分为四个部分，作为值数组返回。

Syntax: BigDecimal.split()

Parameter: BigDecimal values

Return: – sign
– significant_digits
– base
– exponent

示例 #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]

示例 #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]
