Article Introduction：Golang is a high-performance programming language that supports multiple data types, including floating point numbers and integers. In actual development, we sometimes need to convert floating point numbers into integers for some calculations and processing. This article will introduce the methods and techniques of converting floating point numbers to integers in Golang. 1. Forced type conversion In Golang, you can use forced type conversion to convert floating point numbers into integers. For example: ```f := 3.14i := int(f)```In this example, we convert the floating point number 3.14 to an integer

Article Introduction：Floating point numbers are composed of three parts: symbol, exponent code and mantissa. Floating point numbers are divided into single precision floating point numbers and double precision floating point numbers. The range of single precision floating point numbers is -3.4E38~3.4E38, and the range of double precision floating point numbers is -3.4E38~3.4E38. The range is -1.79E+308 ~ +1.79E+308

Article Introduction：Float is the abbreviation of "floating point number". By definition, it is a basic data type built into the compiler for defining numerical values ​​with floating decimal points. Floating-point type variables are variables that can hold real numbers, such as 4320.0, -3.33, or 0.01226. The floating point part of the name refers to the fact that the decimal point can "float", that is, it can support a variable number of numbers before and after the decimal point. float class type minimum size typical size float float4 bytes 4 bytes double8 bytes 8 bytes longdouble8 bytes 8, 12 or 16 bytes float range size range precision 4 bytes ±1.18x10-38to±3.4x1

Article Introduction：Float occupies 4 bytes. Float is a data type that occupies 4 bytes (32 bits) of memory space and is used to store floating point values. It can represent very large or very small numbers and perform mathematical operations. In computers, floating point numbers are represented using floating point number representation, usually using the IEEE 754 standard. When performing floating-point number operations, you need to pay attention to problems that may be caused by rounding errors.

Article Introduction：Use the math.Trunc function to truncate a floating-point number into its integer part and return the truncated floating-point number. Floating-point number is a data type used in computers to represent real numbers (including integers and decimals). However, in practical applications, sometimes we only care about the integer part of the floating point number, and hope to truncate the floating point number and get an integer result. At this time, we can use the Trunc function in the math package to achieve this. The trunc function is a function in the math package of the Go language (Golang) standard library.

Article Introduction：This article will explain in detail the PHP floating point number rounding method. The editor thinks it is very practical, so I share it with you as a reference. I hope you can gain something after reading this article. PHP Floating Point Rounding Overview Floating point numbers are represented in computers as a decimal point followed by an exponent, however, they are often stored in approximations with a limited number of digits. When you need to round a floating point number to a specific precision, there are several ways to do it. Method 1. round() function The round() function rounds a floating point number to the nearest integer. It accepts floating point numbers and optional precision parameters. For example: $num=1.55;echoround($num);//Output: 2echoround($num,1)
