Arbitrary precision decimal floating-point type for Ruby

Hello Rubies,

           Accurately convert numbers  to decimal or exact precision point. Use the Flt gem do discover the below scenario. 

Flt::DecNum is a standards-compliant arbitrary precision decimal floating-point type for Ruby. It is based on the Python Decimal class. 

Usage:

sudo gem install flt

require 'flt'

include Flt

 

x = 0.00000020586

y = Flt::DecNum(x.to_s)

Flt::DecNum.context.precision = 2

puts y/Flt::DecNum(1)

result should be 2.1E-7
