In the actual work, some programs inevitably need to use mathematical functions to calculate, such as the geographical coordinates of the map program to map coordinate transformation. Objective-c, as an extension of ANSI C, uses the mathematical
The Java™ Language Specification version 5th java.lang.Math adds java.lang.StrictMath 10 new methods, and Java 6 adds 10 more. The 1th part of this two-part series introduces a very meaningful new mathematical approach. It provides a function that

This column is mainly about the popular science books of a famous Japanese mathematician, which mainly deals with mathematical antiquity, modern history and some methods of learning maths, and also involves some simple and interesting small topics.
1. Function callIn programming, a function is a name combination of a series of statements used for a certain calculation. When defining a function, you must specify the function name and write a series of program statements. Then, you can use the
