Carry it over to the right. 32 is less than 63 so you will subtract and put a 1 for that value, and continue down the line. 2. Explain why the values 102 and 00102 are the same. Because when you plug the binary numbers into the 8 bit conversion table, the two zeros before the 10 equal nothing.

Intel’s response to the flaw was "An error is only likely to occur [about] once in nine billion random floating point divides", and that "an average spreadsheet user could encounter this subtle flaw once in every 27,000 years of use." (Janeba, 1995) What was the flaw in the Pentium Flaw? The article I read on what the Pentium Flaw was said: “The mathematical basis for the bug: The built-in divider in the Pentium FPU uses a radix 4 SRT algorithm. The strength of this algorithm is that it can compute two (binary) digits of a quotient per step, rather than only one per step as in earlier Intel FPU's. The weakness is that the algorithm needs a stored table of values (a "division table", not unlike a "multiplication table").
The goal formally was to lose or gain no more than one out of every billion billion seconds. That is one second in about 32 billion years, and is 10 to 100 times better than any existing clocks. Already, atomic clocks have come a long way. While experimental clocks are moving ahead, a device called the NIST-F1 is the official U.S. timekeeper. It’s accurate to a few parts in 1016.
By double checking his work, he found that the results differed significantly from theoretical values. An example of this is: 4195835/3145727, discovered by Tim Coe of Vitesse Semiconductors. The correct value is 1.33382 to 6 sig. figs, while the flawed Pentium's floating-point unit computed 1.33374 to 6 sig figs, a relative error of 0.006% (Janeba, 1995). In October 1994, Dr. Nicely contacted Intel support to report the flaw found within their Pentium chip.
