How to use the loop (do-while) In Javascript
In this approach we are using the do while loop where we iterate and convert the decimal input number to the equivalent base by repeatedly calculating the remainders and then creating a result in the reverse order. We check the base is valid or not also.
Example: In this example we are performing decimal to any base conversion using the do-while loop.
function decToBase(inputNumber, inputBase) {
if (inputBase < 2 || inputBase > 36) {
return "Not Valid Base";
}
let tempOutput = "";
let checkNum = false;
if (inputNumber < 0) {
checkNum = true;
inputNumber = Math.abs(inputNumber);
}
do {
let rem = inputNumber % inputBase;
tempOutput = rem + tempOutput;
inputNumber = Math.floor(inputNumber / inputBase);
} while (inputNumber > 0);
if (checkNum) {
tempOutput = "-" + tempOutput;
}
return tempOutput || "0";
}
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:
