Ruby BigDecimal <= 函数

BigDecimal#<=() : <=()是BigDecimal类的一个方法，用于比较两个BigDecimal值。

Syntax:  BigDecimal.<=()

Parameter:  BigDecimal values

Return:  true - if a <= b; otherwise false

代码#1：<=()方法的例子

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

输出:

BigDecimal a <= b : false

BigDecimal b <= c : false

BigDecimal a <= c : true

代码#2：<=()方法的例子

# Ruby code for BigDecimal.<=() 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')
  
# comparing two BigDecimal
puts "BigDecimal a <= b : #{a<=b}\n\n"
  
# comparing two BigDecimal
puts "BigDecimal b <= c : #{b<=c}\n\n"

输出:

BigDecimal a <= b : false

BigDecimal b <= c : true
