Hi, I have a desire to understand the format of IEEE 754 (for example, I chose the addition operation), but I have a problem: the format is not accurately described the formation of the status bits. For example, I found an algorithm that also through the expansion of the mantissa of the result (three bits right) allows you to monitor an inaccurate result (rounding mode - to nearest). I decided to simulate the algorithm and compare the results with my processor intel i7 (Control Register "cwr") and I get different results. Is there a standard (or algorithm) in the public domain, by which Intel generates bit "inexact"?
P.S: I used the article "What Every Computer Scientist Should Know About Floating-Point Arithmetic" DAVID GOLDBERG. For access to the "cwr" register I used delphi 7.
