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.
