Rounding of small numbers in the Java language

1, double Java.lang.Math.floor (double A)Returns the maximum double value (closest to the positive infinity direction) of an integer that is less than or equal to the parameter A in a mathematical sense, special case:If the parameter value equals a mathematical integer, the returned result is the same as the parameter valueIf the parameter is Nan (non-numeric) or infinity or +0 or-0, the return value is the

Mathematical classes in C #, math, floating-point numbers (middle)

The following code is a floating-point number divided by 0: float f1=1; float f2=0; float f3=f1/f3; When you see the code above, you may suddenly think of an exception: Dividedbyzeroexception. If these numbers are integers now, they do, but! These are floating-point numbers and do not produce an exception. In fact, floating-point arithmetic never produces an exception, because F2 is not really 0, it's just a very close to 0 number (how many?). In this case, the F3 equals a special value. It is

Infinitely large constant INF

#define INF 0x3f3f3f3f 0x3f3f3f3f decimal is 1061109567, that is, 10^9 level (and 0x7fffffff (32-bit int maximum) an order of magnitude), and the general situation of the data are less than 10^9, So it can be used as infinity without the case that the data is larger than infinity. On the other hand, since the general data is not greater than 10^9, when we add infinity

Practical Guide-Huawei router configuration

earlier versions, CISCO X25 adopts its own standard Encapsulation Format by default. The encapsulation Format of the Huawei router is the international standard IETF. Therefore, in order to communicate with each other, you need to change the encapsulation Format of the CISCO router to the ietf format by using the command: encapsulation x25 ietf 2. Huawei VRP1.1 and later versions have specially added CISCO-compatible encapsulation formats. In this way, you do not need to change the CISCO Encaps

What is frame relay of PPP?

define the sites that can be directly connected to other sites. You only need to pay a small fee for PVC connection each month. For frame relay, you should also know other related terms: ◆ LMS: Local Management Interface (LMS), which is the Management protocol for Frame Relay. LMIS is sent to communicate with the vswitch about what DLCI is available and whether the network is congested. ◆ DLCI: Data Link C

BP Neural network

BP networks.)② uses the method of probability theory-maximum likelihood estimation to design the error objective function.The mathematical principle of LMS (minimum mean square) used in linear neural networks can be obtained by the maximum likelihood estimation + hypothesis error probability model. (see Andrew Ng Video)The likelihood function's numerical range is larger than the LMS, especially in two case

Brief analysis of "reprint" WEBRTC echo Cancellation module

(0,1), ( 1,0) Additional weight value is 0, and the C code algorithm is in the frame order of the remote and near-end array xor, the actual application can also be used every 1 frames or 2 frames to do XOR, this can expand the search scope.In general, the complexity of the time-delay estimation algorithm of WEBRTC is greatly simplified, especially for the mobile terminal, which is more sensitive to the computation volume. For practical applications, the algorithm also has a space for improvemen

Supervised learning: Stochastic gradient descent algorithm (SGD) and batch gradient descent algorithm (BGD)

we predict H (x) based on this formula, the X in the formula is what we know (the eigenvalues in the sample), but the value of θ is not known , so long as we solve the value of theta, we can make predictions based on this formula.Minimum mean method (Least Mean squares)Before introducing the LMS, let's look at what the concept of loss function is.What we're going to do is to select the optimal theta based on our training set and let H (x) as close to

always follow this line of thinking: I have 4 shards, so it's a very bad idea to use a 4 possible field to do the chip key.Suppose we have an application that stores user information, and each document has a continent field that represents the user's region, and its field values can be "Africa", "Antarctica", "Asia", "Australia", "Europe", "North Ameraica "or" South America ", considering that we have a data center on every continent-perhaps not Antarctica-and want to provide user data for it f

node.By default, a faulty resource can be run on a node only after the administrator manually resets the resource fault count (after the fault cause is fixed.However, you can set the failure-timeout option of the resource to invalidate the fault count. If you set migration-threshold = 2 and failure-timeout = 60 s, the resource will be migrated to the new node after two failures, and it may be allowed to move back after one minute (depending on stickiness and constraint scores ).There are two ex
