php - sorting involving exact decimal point

Question

Now there is a set of data in a format such as 12.244 13.784 10.879 8.976 20.794, and the purpose is to sort. Is there any way to sort according to this format
(The problem lies in what format the field should be in. Int can only be integers. The decimal point cannot be compared, and the sorting function cannot be implemented using varchat, because it counts from the first position)

Answer 1

Field type double
