红宝石 | BigDecimal <= 值
BigDecimal#<=() : <=()是一个 BigDecimal 类方法,它比较两个 BigDecimal 值。
Syntax: BigDecimal.<=()
Parameter: BigDecimal values
Return: true - if a <= b; otherwise false
代码 #1:<=() 方法的示例
# 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:<=() 方法的示例
# 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
