This should have been written before, forgotten, and mended.This time we talk about how to compute the values of mathematical expressions in Java, for example, we want to calculate sin (PI/3) + cos (PI/6) + 5.6^3, how do we calculate it? Here we need to use the Java math built-in function, the so-called built-in function, is the

Fourth mathematical functions, characters and strings 4.2 common mathematical functionsMethods are divided into three categories: trigonometric methods (trigonometric method), exponential function methods (exponent method), and service methods4.4 String TypeThe string type is not a base type, but a reference type (reference type).

The Math class provides a number of commonly used mathematical functions, such as trigonometric, logarithmic, exponential, and so on. A mathematical formula if you want to represent it in code, you can split it and then apply the method under the Math class.
Math.Abs (12.3); 12.3 Returns the absolute value of this number Math.Abs (-12.3); 12.3 Math.copy
