例子 #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"
