Only show decimal point if floating point component is not .00 sprintf/printf
If you're using rails, you can use rails' NumberHelper methods:http://api.rubyonrails.org/classes/ActionView/Helpers/NumberHelper.html
number_with_precision(13.001, precision: 2, strip_insignificant_zeros: true)# => 13number_with_precision(13.005, precision: 2, strip_insignificant_zeros: true)# => 13.01Be careful, because precision means all digits after decimal point in this case.
