# loading library
require 'bigdecimal'
require 'bigdecimal/util'

# declaring bigdecimal
a = BigDecimal("10")

# declaring bigdecimal
b = -BigDecimal("10")

# declaring bigdecimal
c = -BigDecimal("11.43")

# to_f() method
puts "BigDecimal a to_f method : #{a.to_f()}\n\n"

puts "BigDecimal b to_f method : #{b.to_f()}\n\n"

puts "BigDecimal c to_f method : #{c.to_f()}\n\n"

Output :

a = BigDecimal('12')*12

# declaring bigdecimal
b = BigDecimal('10')-(22 ** 7.1) ** 10

# declaring bigdecimal
c = BigDecimal('-3')

# to_f() method
puts "BigDecimal a to_f method : #{a.to_f()}\n\n"

puts "BigDecimal b to_f method : #{b.to_f()}\n\n"
