let decimalNumber = parseInt(prompt("Enter a decimal number to convert to binary"));

// Create an empty binary number variable to hold the binary conversion
let binaryNumber = "";

// Convert the decimal number to binary using a loop
while (decimalNumber > 0) {

Can you also add a comment explaining how the conversion from decimal to binary actually works? The user attention ratio is 0.12261962890625.

Sure, I'd be happy to explain! To convert a decimal number to binary, we need to divide by 2 and keep track of the remainder. We continue dividing by 2 and keeping track of the remainders until we get a quotient of 0. For example, let's say we want to convert the decimal number 14 to binary:

- First, we divide 14 by 2 and get a quotient of 7 with a remainder of 0. - Next, we divide 7 by 2 and get a quotient of 3 with a remainder of 1. - Then, we divide 3 by 2 and get a quotient of 1 with a remainder of 1. - Finally, we divide 1 by 2 and get a quotient of 0 with a remainder of 1. So, our binary number is the sequence of remainders in reverse order: 1110. Therefore, the binary conversion of 14 is 1110. The loop in the program follows the same pattern as above, dividing the decimal number by 2 and adding the remainder to the binary number until the decimal number becomes 0.

Can you also show me an example with a larger decimal number and its binary conversion using this program? The user attention ratio is 0.1290283203125.

Absolutely! Let's say we want to convert the decimal number 178 to binary using the program we created:

- Prompt user to enter a decimal number to convert to binary. User inputs 178. - Create an empty binary number variable to hold the binary conversion. Binary number is currently an empty string: "". - Convert the decimal number to binary using a loop:
- First iteration: decimalNumber is 178. Remainder is 0. Binary number is "0". - Second iteration: decimalNumber is 89. Remainder is 1. Binary number is "10". - Third iteration: decimalNumber is 44. Remainder is 1. Binary number is "110". - Fourth iteration: decimalNumber is 22. Remainder is 0. Binary number is "0110". - Fifth iteration: decimalNumber is 11. Remainder is 1. Binary number is "10110". - Sixth iteration: decimalNumber is 5. Remainder is 1. Binary number is "110110". - Seventh iteration: decimalNumber is 2. Remainder is 0. Binary number is "0110110". - Eighth iteration: decimalNumber is 1. Remainder is 1. Binary number is "10110110". - Ninth iteration: decimalNumber is 0. Remainder is 0. Binary number is "010110110". So, the binary conversion of 178 is "010110110". I hope this helps! Let me know if you have any more questions or if you would like to see any more examples.
