代码#1：abs()方法的例子

# Ruby code for abs() method
  
# loading BigDecimal
require 'bigdecimal'
  
# declaring BigDecimal
a = 42.1**13
  
# declaring BigDecimal
b = -BigDecimal("10")
  
# declaring BigDecimal
c = -(22 ** 7.1) * 10
  
# a
puts "absolute value of a : #{a.abs}\n\n"
  
# b
puts "absolute value of b : #{b.abs}\n\n"
  
# c
puts "absolute value of c : #{c.abs}\n\n"

输出:

absolute value of a : 1.3051704902006439e+21

absolute value of b : 0.1E2

absolute value of c : 33978252067.813686

代码#2：abs()方法的例子

# Ruby code for abs() 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')
  
# a
puts "absolute value of a : #{a.abs}\n\n"
  
# b
puts "absolute value of b : #{b.abs}\n\n"
  
# c
puts "absolute value of c : #{c.abs}\n\n"

输出:

absolute value of a :8916100448229 

absolute value of b : 0.205121100730586399999999999999999999999999999999999999999999999999999999999999999999999999999E96 

absolute value of c : 0.3E1
