Keep in mind while using One's complement and Two's complement that if your first bit is "1" the number will be processed as negative. If you want to enter a positive number please add one extra empty bit "0" in the front. For example if you want to write "7" in binary, write "0111" instead of "111". If you write "111" the first bit will be considered as negation and in Two's complement you will get "-1" and in One's complement "0".
The Binary numeral system is a positional notation with a base of 2. It uses only two digits 0 and 1. Each digit is referred to as a bit. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used by almost all modern computers and computer-based devices.
The modern binary number system was studied in Europe in the 16th and 17th centuries by Thomas Harriot, Juan Caramuel y Lobkowitz, and Gottfried Leibniz. However, systems related to binary numbers have appeared earlier in multiple cultures including ancient Egypt, China, and India. Leibniz was specifically inspired by the Chinese I Ching.
