代码 #1:coerce() 方法的示例
# Ruby code for coerce() method
# loading BigDecimal
require 'bigdecimal'
# declaring BigDecimal
a = 42.1**13
# declaring BigDecimal
b = -BigDecimal("10")
# declaring BigDecimal
c = -(22 ** 7.1) * 10
puts "coerce example 1 : #{a.coerce(b)}\n\n"
puts "coerce example 2 : #{b.coerce(c)}\n\n"
输出 :
coerce example 1 : [-10.0, 1.3051704902006439e+21]
coerce example 2 : [#, #]
代码 #2:coerce() 方法的示例
# Ruby code for coerce() 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')
puts "coerce example 1 : #{a.coerce(b)}\n\n"
puts "coerce example 2 : #{b.coerce(c)}\n\n"
输出 :
coerce example 1 : [-2.051211007305864e+95, 8916100448229.0]
coerce example 2 : [#, #]
