示例 #1:
# Ruby code for BigDecimal.to_i() method
# loading library
require 'bigdecimal'
require 'bigdecimal/util'
# declaring bigdecimal
a = BigDecimal("10")
# declaring bigdecimal
b = -BigDecimal("10")
# declaring bigdecimal
c = -BigDecimal("11.43")
# to_i() method
puts "BigDecimal a to_i method : #{a.to_i()}\n\n"
puts "BigDecimal b to_i method : #{b.to_i()}\n\n"
puts "BigDecimal c to_i method : #{c.to_i()}\n\n"
输出 :
BigDecimal a to_i method : 10
BigDecimal b to_i method : -10
BigDecimal c to_i method : -11
示例 #2:
# Ruby code for BigDecimal.to_i() method
# loading library
require 'bigdecimal'
require 'bigdecimal/util'
# declaring bigdecimal
a = BigDecimal('12')*12
# declaring bigdecimal
b = BigDecimal('10')-(22 ** 7.1) ** 10
# declaring bigdecimal
c = BigDecimal('-3')
# to_i() method
puts "BigDecimal a to_i method : #{a.to_i()}\n\n"
puts "BigDecimal b to_i method : #{b.to_i()}\n\n"
