How to use the Recursion In Javascript
In this approach, we are using the recursive function that converts a input decimal number to its equivalent base. This apporach also properly validates the base range and gives correct output.
Example: In this example, we are performing decimal to any base conversion using Recursion
function decToBase(inputNumber, inputBase) {
if (inputBase < 2 || inputBase > 36) {
return "Not Vaild Base";
}
if (inputNumber === 0) {
return '0';
}
let rem = inputNumber % inputBase;
let quo = Math.floor(inputNumber / inputBase);
if (quo === 0) {
return rem.toString();
} else {
return decToBase(quo, inputBase) + rem.toString();
}
}
let inputNo = 1100;
let inputBase = 2;
let output = decToBase(inputNo, inputBase);
console.log
(`The Decimal ${inputNo} in base ${inputBase} is: ${output}`);
Output
The Decimal 1100 in base 2 is: 10001001100
JavaScript Program for Decimal to any base conversion
In this JavaScript article, we will see how we can do decimal to any base conversion in JavaScript. The base can not be less than 2 and can not exceed 36, So we always have to find out the base of a decimal that lies in between this range, which is ‘2=< base <=36’.
Example:
Input: number = "1100", base = 2
Output: 10001001100
There are different types of methods to perform decimal to any base conversion in JavaScript:
