Standard 12-point hex socket bits and wrenches fit these screws. The screw heads are typically flanged, and may fit into standard Allen hex socket cap screw counterbores molded or machined into parts to be fastened. Compared to Allen hex sockets, the advantages of these bolts include higher torque capability and the lack of a recess to trap water.
Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.
A common example is the Data General Nova, which was a 16-bit design that performed 16-bit math as a series of four 4-bit operations. 4-bits was the word size of a widely available single-chip ALU and thus allowed for inexpensive implementation. Using the definition being applied to the 68000, the Nova would be a 4-bit computer, or 4/16.
Zero (0.0) is represented in normalized form as all zero bits, which is arithmetically the value +0.0 16 × 16 0 − 64 = +0 × 16 −64 ≈ +0.000000 × 10 −79 = 0. Given a fraction of all-bits zero, any combination of positive or negative sign bit and a non-zero biased exponent will yield a value arithmetically equal to zero.
In 1973, ECMA-35 and ISO 2022 [17] attempted to define a method so an 8-bit "extended ASCII" code could be converted to a corresponding 7-bit code, and vice versa. [18] In a 7-bit environment, the Shift Out would change the meaning of the 96 bytes 0x20 through 0x7F [a] [20] (i.e. all but the C0 control codes), to be the characters that an 8-bit environment would print if it used the same code ...
Hextet would more properly describe a 6-bit aggregation, whereas the exact term for 16 bits should be hexadectet, directly related to the term octet (for 8 bits). However, because it is harder to pronounce, the short form hextet is used—in analogy to how hex is commonly used as an abbreviation for hexadecimal in computing.
