Woah, really cool. My understanding is that Posit, the successor to unum versions 1 and 2, is the future and is much easier to implement in hardware [0]. [0]:

There is a Posit BoF at SC17 (supercomputing) Nov 14 DEN: http://sc17.supercomputing.org/presentation/?id=bof135&sess=sess333 http://sc17.supercomputing.org/presentation/?id=bof135&sess=... Posit Paper: http://johngustafson.net/pdfs/BeatingFloatingPoint.pdf http://johngustafson.net/pdfs/BeatingFloatingPoint.pdf A new data type called a posit is designed as a direct drop-in replacement for IEEE Standard 754 floating-point numbers (floats). Unlike earlier forms of universal number (unum) arithmetic, posits do not require interval arithmetic or variable size operands; like floats, they round if an answer is inexact. However, they provide compelling advantages over floats, including larger dynamic range, higher accuracy, better closure, bitwise identical results across systems, simpler hardware, and simpler exception handling. source: https://twitter.com/daniel_bilar/status/920252363159539712 https://twitter.com/daniel_bilar/status/920252363159539712
