例子 #1 :
# Ruby code for BigDecimal.to_s() 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_s() method
puts "BigDecimal a to_s method : #{a.to_s()}\n\n"
puts "BigDecimal b to_s method : #{b.to_s()}\n\n"
puts "BigDecimal c to_s method : #{c.to_s()}\n\n"
输出:
BigDecimal a to_s method : 0.1E2
BigDecimal b to_s method : -0.1E2
BigDecimal c to_s method : -0.1143E2
例子 #2 :
# Ruby code for BigDecimal.to_s() 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_s() method
puts "BigDecimal a to_s method : #{a.to_s()}\n\n"
puts "BigDecimal b to_s method : #{b.to_s()}\n\n"
puts "BigDecimal c to_s method : #{c.to_s()}\n\n"
输出:
BigDecimal a to_s method : 0.144E3
BigDecimal b to_s method : -0.20512110073058639999999999999999999999999999999999999999999999999999999999999999999999999999999E96
