Today, I would like to share with you how to convert binary to hexadecimal in JavaScript. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article.

The method of converting binary to hexadecimal in JavaScript

Vara=100

Varb=parseInt (a par 2)

Tostrin (16)

Introduction to related functions:

ParseInt () parses the string and returns an integer.

ParseInt () determines the cardinality based on the string when the value of the parameter radix is 0, or when the parameter is not set.

When the parameter cardinality is ignored, the cardinality of the JavaScript default number is as follows:

If the string starts with "0x", parseInt () parses the rest of the string into hexadecimal integers.

ECMAScript v3 allows the implementation of parseInt () to parse the following characters into octal or hexadecimal numbers if the string begins with 0.

If the string begins with a number between 1 and 9, parseInt () parses it to a decimal integer.

Grammar

Parse (string, cardinality)

Function converts an Number object to a string and returns the result.

Grammar

Number.toString (cardinality)

Binary conversion:

1. Conversion between decimal and binary, octal and hexadecimal

Vara=111, decimal to binary

A.toString (2) 2, decimal to octal

A.toString (8) 3, decimal to hexadecimal

A.toString (16) binary, binary, octal, hexadecimal and decimal conversion

1, binary to decimal

Varb=100

ParseInt (bmeme2); 2, octal to decimal

Varc=100

ParseInt (cPol 8); 3. Conversion from hexadecimal to decimal

Vard=100

ParseInt (dline 16)
