The most significant binary digit, or bit, of a signed binary number. If set to a logic 1, this bit represents a negative quantity.

A single bit, usually the most significant bit in a word, which is used to designate the algebraic sign of the information contained in the remainder of the word.

The most significant (leftmost) bit of a number field, usually set to 1 if the number is negative. When an 8-bit value is added to a 16-bit value using signed arithmetic, the microprocessor propagates the sign bit through the high order half of the 16-bit register holding the 8-bit value in a process called sign extension or sign propagation.

In a floating-point representation, the bit that indicates the sign of the value. In IEEE formats, the sign bit is the leftmost bit. See also exponent, fraction.

Bit (or bits) in a signed binary number that indicates whether the number is positive or negative. See also binary number, bit

The first bit in a dibit (group of two bits) in 2 binary, 1 quarternary (2B1Q) modulation. The sign bit determines if the voltage of the transmitted signal is positive or negative. The second bit is the magnitude bit, and it determines whether the voltage is positive or negative.

The bit of a single, double, or double-double number that indicates the number's sign: 0 indicates a positive number; 1, a negative number.

Binary bit that is added to the leftmost position of a binary number to indicate whether that number represents a positive or a negative quantity./ When used as an output label inside an IEEE/ANSI symbol, indication of seperation of two functions.

In computer science the sign bit is the bit in a computer numbering format which indicates the sign of the number. Typically the bit is the most significant bit in the format. Typically if the sign bit is 1 the number is negative (in the case of two's complement integers) or non-positive (for the case of ones' complement integers, sign-magnitude integers, and floating point numbers).
