woodpecker 0 #1 December 2, 2007 Anyone up to speed on these. I ran into a little snag: I'm adding the following two decimal numbers together. They are both stored in excess-50 floating point format, with the decimal point to the left of the first mantissa digit. A (0) is used for positive and a (9) used for negative. 05012500 95325750 An easier way to see this problem is to break it down. 0.12500 x 10^0 added to -0.25750 x 10^3SONIC WOODY #146 There is a fine line between cockiness and confidence -- which side of the line are you on?

woodpecker 0 #4 December 2, 2007 How about a check of my work and help from there. Here is what I did: 05012500 95325750 First I inverted the numbers since the negative was the larger. Since I’m adding a larger negative, technically, I’m subtracting the smaller number. New equation: 95325750 05012500 Then I converted the exponents to match the larger of the numbers (number on top) 95325750 05300012 Then added subtracted the two numbers Answer = 95025738 And when rounded 95025740 = -0.25740 x 10^0SONIC WOODY #146 There is a fine line between cockiness and confidence -- which side of the line are you on?

grannyinthesky 0 #5 December 2, 2007 You've got .125 + (-257.50) = -257.375 if you just convert to standard decimal notation. A scientific or graphing calculator would let you just add the numbers in scientific notation form without the conversions. Pat"safety first... and What the hell..... safety second, Too!!!

grannyinthesky 0 #6 December 2, 2007 Your work is great. I hadn't thought of doing them in the given form, but the work and answers match mine. Just curious, where is the problem from?

woodpecker 0 #7 December 2, 2007 I'm taking CMIS 310 "The architecture of computer hardware and systems software" to finish up my degree and it was one of the summary questions. Architecture is my weakness in computers. I hate it. I mean who really cares about 9's compliment, BCD, and floating integers. lol Thanks for the help.

FlyboySMB 0 #9 December 2, 2007 My Calc/Diff Eqs Prof always asked the same question from all the engineering students....."what are some examples of how this math is used in the real world" She was so curious she went back to school & got an engineering degree with some of her own students!

turtlespeed 226 #11 December 2, 2007 I have a few floating point integers for you - but they all are derived from a formation designed from manipulating and folding in most of the phalanges in my right hand at the metacarporealphalageal joint, simultaneously leaving the phalanges aligned linearly with the metacarpals in the second finger.I'm not usually into the whole 3-way thing, but you got me a little excited with that. - Skymama BTR #1 / OTB^5 Official #2 / Hellfish #408 / VSCR #108/Tortuga/Orfun Quote Share this post Link to post Share on other sites

grannyinthesky 0 #20 December 3, 2007 The 10^3 moves the decimal place three to the right which makes that term -257.50. Since 10^0 is just 1, you just add the .12500 to that."safety first... and What the hell..... safety second, Too!!! " ~~jmy POPS #10490 Quote Share this post Link to post Share on other sites
