如何将两个零的 00 打印为整数? [英] How do to print two zero's 00 as an integer?

问题描述

我正在研究一些应用学院练习题，但我似乎无法打印两个 00 以进行时间转换.这是我到目前为止所拥有的:

I'm working on some app academy practice questions and I can't seem to print two 00's for my time conversion. Here's what I have so far:

def time_conversion(minutes)
  hours = minutes/60            
  if minutes%60 < 10
    minutes = minutes%60
  elsif minutes%60 > 10
    minutes = minutes%60
  elsif minutes%60 == 0
    minutes = 00
  end        

  return "#{hours}:#{minutes}"
end

time_conversion(360)

推荐答案

您可以使用 sprintf:

You can use sprintf:

sprintf("%02d:%02d", hours, minutes)

或等效的 String#%

"%02d:%02d" % [hours, minutes]
