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)
