Course Introduction:The PHPBCMath extension is a powerful tool in the PHP standard library. It provides a rich function library that can handle complex calculations such as large numbers, decimals, and fractions. Compared with PHP's built-in mathematical operators and functions, BCMath extensions can provide higher precision and a wider range of operations to meet the needs of high-precision mathematical calculations in various fields such as science, engineering, and finance. In order to use the BCMath extension, you need to include the following code in your PHP script: Among them, the bcscale() function is used to set the number of digits after the decimal point. The default value is 0, which means no decimals are retained. You can adjust this value as needed to control calculation accuracy

Course Introduction:1. Introduction to BCMath The BCMath extension is a PHP built-in extension that provides high-precision mathematical calculation capabilities, supports up to 16 digits of precision after the decimal point, and meets the needs of various complex mathematical operations. 2. BCMath function BCMath provides a rich and practical function library, covering basic mathematical operations, carry conversion, trigonometric functions, exponential functions, logarithmic functions, etc. 3. Install and configure BCMath as a standard extension of php. There is no need to install it separately, but it needs to be enabled in php.ini. You can activate the BCMath extension by modifying the extension=bcmath option in php.ini and restarting the PHP service. 4. Usage example //Addition $result=

Course Introduction:PHP is a very popular server-side programming language. It is not only easy to learn and use, but also provides a wealth of built-in functions and extensions, which is very suitable for processing various types of data. One of them is high-precision calculation. This article will introduce high-precision calculation and its related functions in PHP. 1. What is high-precision computing? In computers, data is usually stored in binary form, so the size of numbers is limited by the data type. For example, a 32-bit integer type can only represent a maximum of $2^{31}-1$. Beyond this, Overflow occurs when the range is exceeded. Ran

Course Introduction:Recently, PHP8 version has been officially released, bringing many thoughtful updates and new features to developers. Among them, the introduction of the fdiv() function has brought good news to developers who perform high-precision calculations. The fdiv() function is a new function in PHP8 that is used to calculate high-precision values. It can perform more refined calculations in PHP development. As the accuracy of data calculations increases, developers have also put forward higher requirements for the accuracy of data calculations. The emergence of the fdiv() function just solves this kind of problem.

Course Introduction:In PHP, the bcscale() function is used to set the default parameter functions of all bcmath. This function sets the default scale parameter for all subsequent calls to BC math functions if no scale parameter is explicitly specified. Syntax intbcscale($scale) parameter The $bcscale() parameter accepts only one parameter, which is a required integer type parameter. This parameter represents the number of digits after the decimal point. The default value is 0. Return value The $bcscale() function returns the old precision value. Example 1<?php //defaultscale:5 bcscal
