+To convert the integer numbers into human readable format.
+
+```ruby
+number_to_human(123)                                          # => "123"
+number_to_human(1234)                                         # => "1.23 Thousand"
+number_to_human(12345)                                        # => "12.3 Thousand"
+number_to_human(1234567)                                      # => "1.23 Million"
+number_to_human(1234567890)                                   # => "1.23 Billion"
+number_to_human(1234567890123)                                # => "1.23 Trillion"
+number_to_human(1234567890123456)                             # => "1.23 Quadrillion"
+number_to_human(1234567890123456789)                          # => "1230 Quadrillion"
+number_to_human(489939, precision: 2)                         # => "490 Thousand"
+number_to_human(489939, precision: 4)                         # => "489.9 Thousand"
+number_to_human(1234567, precision: 4,
+                        significant: false)                   # => "1.2346 Million"
+number_to_human(1234567, precision: 1,
+                        separator: ',',
+                        significant: false)                   # => "1,2 Million"
+
+number_to_human(500000000, precision: 5)                      # => "500 Million"
+number_to_human(12345012345, significant: false)              # => "12.345 Billion"
+```
+
+Non-significant zeros after the decimal separator are stripped out by default (set :strip_insignificant_zeros to false to change that):
+
+```ruby
+number_to_human(12.0000) # => “12” 
+number_to_human(12.0000, precision: 4, strip_insignificant_zeros: false) # => “12.00”
+```
+
+### Troubleshooting
+
+If you receive the following error 
+
+```
+NoMethodError: undefined method `number_to_human' for main:Object
+```
+
+include NumberHelper in your controller / views.
+
+```ruby
+include ActionView::Helpers::NumberHelper
+```
