I feel like a crazy person. I'd like to round all fractions up to the nearest whole number.
For example, 67/30 = 2.233333333334. I would like to round that up to 3. If the result is not a whole number, I never want to round down, only up.
This is what I'm trying:
puts 67/30.to_f.ceil Here are examples of what I'm looking for:
Any ideas? Thanks much!

Ruby Language Numbers Rounding Numbers The round method will round a number up if the first digit after its decimal place is 5 or higher and round down if that digit is 4 or lower.
The round() method can be used to round a number to a specified number of decimal places in Ruby. We can use it without a parameter ( round() ) or with a parameter ( round(n) ). n here means the number of decimal places to round it to.
Ruby | Numeric round() function The round() is an inbuilt method in Ruby returns a number rounded to a number nearest to the given number with a precision of the given number of digits after the decimal point. In case the number of digits is not given, the default value is taken to be zero.
The problem is that you're currently calling ceil on 30.to_f. Here's how Ruby evaluates it:
(67)/(30.to_f.ceil) # .ceil turns the float into an integer again (67)/(30.0.ceil) # and now it's just an integer division, which will be 2 67/30 # = 2 To solve this, you can just add parenthesis:
puts (67/30.to_f).ceil # = 3 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
