A sixteen-bit floating-point representation with one sign bit, five exponent bits and ten stored fraction bits. For sign , stored exponent and fraction integer , normal finite values areThe implicit leading one gives eleven significant binary digits. With , the value is , including signed zero at and subnormal numbers otherwise. The stored exponent is reserved for infinities at and NaN otherwise. The positive normal range is through ; the least positive subnormal number is .

Half-precision floating-point format, often referred to as "half" or "binary16," is a computer number format that occupies 16 bits (2 bytes) in memory and is typically used for representing floating-point numbers with lower precision and range than single-precision (float) or double-precision (double) formats.
