SASCommon function
I. mathematical functions
ABS(x) Find the absolute value of X.
MAX(x1,x2,…,xn) Find the largest one in all independent variables.
MIN(x1,x2,…,xn) Find the smallest of all independent variables.
MOD(x,y) X is divided by the remainder of y.
SQRT(x) Seek the square root of X.
ROUND(x,eps) For example, the ROUND (5654.5654, 0.01) result is 5654.57, and the ROUND (5654.5654, 10) result is 5650.
CEIL(x) The smallest integer that is greater than or equal to X. When x is integer, it is x itself, otherwise it is the nearest integer on the right side of X.

The engineer who designs the Android is still very standard, and at the first glance, he knows what it means. RemoteViews, as the name suggests, remote View. Android in order to enable the process A to display the View of the process B, this kind of View is designed.It’s not a real View. In fact, we used RemoteViews to send notifications to the status bar. Let’s get to know about RemoteViews.
Let’s take a look at how RemoteViews works with Notification:

1 . How to deal with those pyx and.C.H files
Some files under lib are.Pyx files, encounter the file that can not be imported cython, and then make the Lib folder again.
The operation of.C and.H is the same.
2 . It’s best not to use pretrained_model when training your own data, because the type of training varies, loss = inf and loss = nan, – Nan may occur.
3 . Data source checking:
When you’re making your own VOC format data source, check the contents of the. XML file to see if it’s consistent with groudtruth, or the training won’t converge. (pr...
This paper summarizes the commonly used brushes used to STL containers and some standard algorithms, including:
string、vector、map、pair、unordered_map、set、queue、priority_queue、stack，And the common operations of these containers, such as insertion, deletion, lookup, access (iterator or subscript, C++ 11 keyword auto understand? Sequential access to or random access), initialization, etc. Finally, we introduce several common functions of header files <, algorithm> and below.In particular, sort.

First of all, as long as you can make good use of Baidu bidding is a good thing, it can be said that all these years, I have been eating this meal Baidu, so I am very grateful to Baidu. This article is not to say that Baidu is not good. It is just a matter of fact. Only by understanding it can we make good use of it.
Here refers to the operation of the account, the other does not say, Baidu bidding in those unknown rules and cat greasy, many, give a few examples to illustrate briefly:
