In the z/OS operating system, the floating-point number type is divided into binary floating-point number schema BFP, hexadecimal floating-point architecture hfp and decimal floating-point architecture DFP three categories. IBM has established HFP as its base floating point architecture since 1964 s/360 system, 1998 S/390 system formally introduced BFP, that is ieee754-1985 Standard, to 2007 Z9 system began to support DFP, namely ieee754-2008 standard

For UNIX itself, there are also various titles. IBM® mainframe users say a variety of jargon with the letter "Z", such as IBM z/os® and System z9 Virtual Machine (Z/VM), nested system developers use the word eCos, and other UNIX-like flavors mentioned in the chat, such as Linux ®, FreeBSD, Sun Solaris, and Mac OS x. Modern information technology uses a variety of dialects, almost like the story of the Betta of the Bible.
