示例 #1:
# Ruby code for BigDecimal.remainder() method
# loading library
require 'bigdecimal'
# declaring bigdecimal
a = 42.1**13
# declaring bigdecimal
b = -BigDecimal("10")
# declaring bigdecimal
c = -(22 ** 7.1) * 10
# a
puts "BigDecimal a remainder b : #{a.remainder(b)}\n\n"
# b
puts "BigDecimal b remainder c : #{b.remainder(c)}\n\n"
# c
puts "BigDecimal a remainder c : #{c.remainder(a)}\n\n"
输出 :
BigDecimal a remainder b : 0.0
BigDecimal b remainder c : -0.1E2
BigDecimal a remainder c : -33978318848.0
示例 #2:
# Ruby code for BigDecimal.remainder() method
# loading library
require 'bigdecimal'
# declaring bigdecimal
a = 12**12 - 27
# declaring bigdecimal
b = BigDecimal('10')-(22 ** 7.1) ** 10
# declaring bigdecimal
c = BigDecimal('-3')
# a
puts "BigDecimal a remainder b : #{a.remainder(b)}\n\n"
# b
puts "BigDecimal b remainder c : #{b.remainder(c)}\n\n"
# c
puts "BigDecimal a remainder c : #{c.remainder(a)}\n\n"
输出 :
BigDecimal a remainder b : 0.8916100448229E13
BigDecimal b remainder c : -0.2E1
BigDecimal a remainder c : -0.3E1
