I need someone to check my code for the extra credit for the "Numbers" section on the "Ruby Foundations" track. HELP!

Am I satisfying the requirements for the extra credit question on the "Numbers" section on the "Ruby Foundations" Track? If not, please help!

Here is the code challenge: "Try writing a Ruby program that asks a user to input numbers and then multiplies them together. Have the program print out the result to two decimal places regardless of whether or not the user entered an integer or floating point number."

Thanks in advance!

puts "Enter your number please." input = gets.chomp puts "Enter your second number please." second = gets.chomp puts input.to_i.round(3) * second.to_i.round(3)

Hey Erik,

Overall it looks good but it does not round to 2 decimal places wether you test it with floats or integers.

Try this instead:

puts "Enter your number please." 
input = gets.chomp.to_f
puts "Enter your second number please." 
second = gets.chomp.to_f
total = input * second
puts sprintf "%.2f", total

Cheers
