例子 #1 :
# Ruby code for BigDecimal.to_int() 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_int() method
puts "BigDecimal a to_int method : #{a.to_int()}\n\n"
puts "BigDecimal b to_int method : #{b.to_int()}\n\n"
puts "BigDecimal c to_int method : #{c.to_int()}\n\n"
输出:
BigDecimal a to_int method : 10
BigDecimal b to_int method : -10
BigDecimal c to_int method : -11
例子 #2 :
# Ruby code for BigDecimal.to_int() 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_int() method
puts "BigDecimal a to_int method : #{a.to_int()}\n\n"
puts "BigDecimal b to_int method : #{b.to_int()}\n\n"
puts "BigDecimal c to_int method : #{c.to_int()}\n\n"
输出:
BigDecimal a to_int method : 144
BigDecimal b to_int method : -205121100730586399999999999999999999999999999999999999999999999999999999999999999999999999999990
