In PHP, round means "rounding" and is a built-in function that converts floating point numbers into integers. This function can round floating point numbers and return an integer value of type float. The syntax is "round(number, precision,mode);".

The round() function is a very useful function in the PHP number formatting library, which can round floating point numbers to a specified number of decimal places. However, since PHP's division operation may suffer from infinite decimals or loss of precision, rounding of the divisor is also necessary. Next, we will explain in detail how to use PHP's round() function to divide and round.

This article will explain in detail how to format a GMT/UTC date/time with PHP. The editor thinks it is quite practical, so I share it with you as a reference. I hope you can gain something after reading this article. Introduction to Formatting GMT/UTC Date/Time in PHP In PHP, formatting GMT/UTC date/time is crucial for correctly displaying and handling cross-time zone dates. This article will explain how to format a GMT/UTC date/time using PHP's DateTime class, as well as the various formatting options available. DateTime class The DateTime class represents a date and time. It can store and manipulate date/time values in time zones such as GMT/UTC. To create a new Da

How to use the ROUND function in MySQL to intercept the number of decimal places. In MySQL, you can use the ROUND function to intercept the number of decimal places. The ROUND function rounds a number to a specified number of decimal places. The following will introduce you to the use of ROUND function in detail and provide code examples. Syntax: ROUND(X,D)X represents the number to be rounded, and D represents the number of decimal places to be retained. Example of using the ROUND function to intercept the number of decimal places: Suppose there is a table named produc

1The basic unit of Unicode computer storage is the byte, which is composed of 8 bits. Since English only consists of 26 letters plus a number of symbols, English characters can be stored directly in bytes. But other languages (such as Chinese, Japanese, Korean, etc.) have to use multiple bytes for encoding due to the large number of characters. With the spread of computer technology, non-Latin character encoding technology continues to develop, but there are still two major limitations: no multi-language support: the encoding scheme of one language cannot be used in another language and there is no unified standard: for example There are many encoding standards in Chinese such as GBK, GB2312, GB18030, etc. Since the encoding methods are not unified, developers need to convert back and forth between different encodings, and many errors will inevitably occur.

What are the similarities and differences between __str__ and __repr__? We all know the representation of strings. Python's built-in function repr() can express objects in the form of strings to facilitate our identification. This is the "string representation". repr() obtains the string representation of an object through the special method __repr__. If __repr__ is not implemented, when we print an instance of a vector to the console, the resulting string may be. >>>classExample:pass>>>print(str(Example()))>>>

In Python, `format` is a built-in function used to format strings. It is used to create a string template with placeholders and fill the placeholders with specified values. This allows strings to be constructed dynamically based on different situations, making the output more readable and customizable.

The usage of format in python is basic usage, specifying location, specifying variable name, formatting numbers, formatting date and time.
