Decimal To Binary Converter

Decimal to binary conversion is a fundamental process in computer science and digital systems. Our Decimal to Binary Converter tool provides an efficient and user-friendly way to convert decimal numbers (including negative and floating-point numbers) to their binary equivalents. This guide explains the conversion process and the features of our tool.

What is Binary?

Binary is a base-2 number system that uses only two digits: 0 and 1. It is the fundamental language of computers and digital systems. Each digit in a binary number is called a bit (binary digit), and groups of 8 bits form a byte.

The Mathematics Behind Decimal to Binary Conversion

Integer Conversion

13 ÷ 2 = 6 remainder 1 6 ÷ 2 = 3 remainder 0 3 ÷ 2 = 1 remainder 1 1 ÷ 2 = 0 remainder 1 Reading remainders from bottom up: 1101

Fractional Conversion

0.625 × 2 = 1.25 → 1 0.25 × 2 = 0.5 → 0 0.5 × 2 = 1.0 → 1 Result: 0.101

Implementation Details

Core Conversion Logic

function decimalToBinary(decimal) { let num = parseFloat(decimal); let sign = num < 0 ? "-" : ""; num = Math.abs(num); let integerPart = Math.floor(num); let fractionPart = num - integerPart; // Convert integer part let integerBinary = integerPart.toString(2); // Convert fractional part let fractionBinary = ""; while (fractionPart > 0 && precision > 0) { fractionPart *= 2; fractionBinary += Math.floor(fractionPart); fractionPart -= Math.floor(fractionPart); precision--; } return sign + integerBinary + (fractionBinary ? "." + fractionBinary : ""); }
