The Decimal to One's Complement Calculator is an online tool that effortlessly converts decimal numbers into their corresponding one's complement binary values. This calculator is especially useful for those studying computer science or working in fields that require binary calculations. It accepts any integer—positive or negative—and converts it into a binary number, then inverts each bit to yield the one's complement.
Formula of Decimal to One's Complement Calculator
To understand how the calculator works, it's essential to follow the conversion process:
- Convert the decimal number to binary:
- If the decimal number is positive, convert it directly to binary.
- If the decimal number is negative, first convert the absolute value of the number to binary.
- Invert the binary digits:
- Replace all 0s with 1s and all 1s with 0s. This inversion gives you the one's complement of the original decimal number.
Table of Useful Conversions
To aid in understanding and to provide a quick reference, here’s a table of common decimal numbers and their one’s complement in binary:
| Decimal Number | Binary Representation | One's Complement |
|---|---|---|
| 5 | 0101 | 1010 |
| -5 | 0101 | 1010 |
| 10 | 1010 | 0101 |
| -10 | 1010 | 0101 |
| ... | ... | ... |
This table can serve as a handy guide for common conversions without the need for calculations.
Example of Decimal to One's Complement Calculator
Consider the decimal number -5. Here’s how the calculator processes this number:
- Convert -5 to its absolute value, which is 5.
- Binary of 5 is 0101.
- Inverting 0101 yields 1010, which is the one's complement of -5.
