Code #1 : Example for <=>() method

# 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

# a > b
puts "BigDecimal a <=> b : #{a<=>b}\n\n"

# b > c
puts "BigDecimal b <=> c : #{b<=>c}\n\n"

# c < a
puts "BigDecimal a <=> c : #{c<=>a}\n\n"

Output :

BigDecimal a <=> b : 1

BigDecimal b <=> c : 1

BigDecimal a <=> c : -1

Code #2 : Example for <=>() method

# 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')

# a > b
puts "BigDecimal a <=> b : #{a<=>b}\n\n"

# b < c
puts "BigDecimal b <=> c : #{b<=>c}\n\n"

Output :

BigDecimal a <=> b : 1

BigDecimal b <=> c : -1
