代码 #1:*() 方法示例
Ruby
# 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
# multiplicative value
puts "BigDecimal a * b : #{a*b}\n\n"
# multiplicative value
puts "BigDecimal b * c : #{b*c}\n\n"
# multiplicative value
puts "BigDecimal a * c : #{c*a}\n\n"
Ruby
# 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')
# multiplicative value
puts "BigDecimal a * b : #{a*b}\n\n"
# multiplicative value
puts "BigDecimal b * c : #{b*c}\n\n"
# multiplicative value
puts "BigDecimal a * c : #{c*a}\n\n"
输出 :
BigDecimal a * b : -0.1305170490200644E23
BigDecimal b * c : 0.8645901738210328E23
BigDecimal a * c : -1.1284375809886571e+43
