以下返回 (5/12)，一个 Rational 对象。
d = DateTime.current
d2 = d + 10.hours
d2 - d
我如何得到两个时间点的分钟差？
最佳答案
(d2 - d).class
=> Rational
Rational: A rational number can be represented as a paired integer number; a/b (b>0). Where a is numerator and b is denominator. Integer a equals rational a/1 mathematically.
d2 - d
=> (5/12) #get the number of days
((d2 - d) * 24 * 60).to_i
=> 600 # get the number of minutes
