Document Summary

Integer part is the first bit to the right of the point. The conversion from binary to octal is easily accomplished by partitioning the binary number into groups of three bits each and assigning. Converting from binary to hexadecimal is similar except the number is partitioned into groups of four bits. Unsigned numbers are always assumed to be non-negative. Signed numbers sign is determined by the sign bit (left most bit) Overflow - the result of an operation is out of the domain. To calculate r"s complement -> change 1"s and 0"s then add one. Signed numbers can be represented in three ways. For unsigned numbers -> carry out of 1. 2"s complement representation of signed numbers -> addends have same sign but the sign of the sum is different or carry into the sign bit position and carry out of the sign bit condition are different. Binary info is subject to external noise that can change 0s and 1s.
