C # math. Round () Achieves Chinese rounding
Math. Round () in C # does not use the "Rounding" method. In fact, in VB, VBScript, C #, J #, T-SQL in the round function are using banker's rounding (Banker algorithm), namely:Four Homes, six in five

In math. when performing data processing, round often encounters a situation where 81.25 retains a decimal number, and the value is 81.2. It is searched by material and math. the round rounding algorithm adopts the banker's rounding algorithm, which

Msdn does not provide a detailed description. An example is provided;
Math. Round (3.44, 1); // returns 3.4.math.round (3.45, 1); // returns 3.4.math.round (3.46, 1); // returns 3.5.
According to his example, the result is "five homes and six

These three functions may be confusing for beginners. Now I am learning them and I will make a detailed record.
Math. Round () literally knows what it means. How can we get a number around a double or float number? The answer is rounding.
For

Math is a mathematical class in Java, which records many of them.ProgramMathematical aspects to be used, such as two constants:
The circumference rate of the math. Pi record
Math. E records the constant of E.
Math has some similar constants,

These three methods are a headache. After a burst of searches, We will summarize them as follows: Math. Round: If the parameter is a decimal number, rounding itself. Math. ceil: If the parameter is a decimal number, the smallest integer is obtained

I haven't used the math class for a long time. I cannot remember it clearly, so that I can make mistakes when I read a scjp question. I will refresh my memory today. Remember!
Public class t {public static void main (string [] ARGs) {system. out.

Use the js Math. random () function to generate random numbers between n and m.
Abstract:
This article explains how to use js to generate random numbers between n and m. The main purpose is to prepare for later JavaScript code generation.
The Math.

The circumference rate of the Math. PI record
Math. E records the constant of e.
Math has some similar constants, which are commonly used in Engineering Mathematics.
Math. abs evaluate absolute value
Math. sin sine function Math. asin arcsin

Static class: provides constant and static methods for trigonometric functions, logarithm functions, and other general mathematical functions.
Math. Abs (); returns the absolute value of the specified number, decimal double int16 int32 int64 single
