Question

I have output like the following exponential numbers.

6.0e-07

8.1e-07

1.1e-09

But I want above numbers should be displayed like below

0.00000060

0.00000081

0.0000000011

I mean in the form decimal format. I surfed in the net. I could not find any solution for this.

Is it possible in ruby?. if yes How to do that?.

Answer 1

You could use BigDecimal#to_s:

require 'bigdecimal'

BigDecimal.new('6.0e-07').to_s('F') #=> "0.0000006"
BigDecimal.new('8.1e-07').to_s('F') #=> "0.00000081"
BigDecimal.new('1.1e-09').to_s('F') #=> "0.0000000011"
