Tricky rounded Issuie

Hello

I have a file of numbers I've read as a spreadsheet.  The figures are all three long decimals, such as 0.466, however when the file is read some of the numbers get redundant, as additional values 0.4660000000000000250.  I tried all sorts of things to round the values to 3 decimal places (IE, return to 0.466) but nothing works.  See attached the vi in Labview 8.6 to see what I mean.  Does anyone have any suggestions?  I feel like there is something really obvious that I'm missing.

Steve

What you see is what has been raised in this forum more times that I can count, and I learned to count really high school. Computers cannot store numbers of floating points exactly. See http://en.wikipedia.org/wiki/Floating_point_number#Accuracy_problems.

    the only problem is when it comes '9' otherwise it's cool
    Example: (45.86,1) - thin result - 45.9
    But (45.96,1) - is tricky because we get a whole number without fractions :)

    Don't let how a number is displayed confused you. 46 is the same number as 46.0, and they are both exactly the same as 46.00000000000.

    45.9x, where x is a digit, rounded down to 45,9, or rounded up to 46.0. (If you use the display of the number by default, 46.0 will be displayed as 46, without decimal point, but, once again, it is exactly the same number as 46.0.) 45.96 is closer to 46.0 is 45.9, so it will be rounded upwards.

  • Distance and rounds of training swimming errors

    Hello...

    I have the new Apple Watch series 2. I make the swim in our pool inner community twice a week, and I used the new watch swimming twice now. Both times the watch Gets the distance of towers and evil. Here are some details:

    Our community pool is 25 yards - long we checked this by measuring it ourselves. I use the session pool swim.

    The first time I used the watch, I swam 44 laps, which is 1 100 yards. Training app reported that I had made 62 laps and 1 550 yards.

    The second time (today), I swam 50 laps, which is 1250 yards. Training app reported that I had made, 80 laps and 2000 yards.

    I always swim in the same way,-1 lap breaststroke of 2 rounds side stroke, rear race 1 lap. Then, again. I don't have flip turn.

    Any ideas or help greatly appreciated.

    Hello

    It seems that Firefox has issues with the rounded buttons (AFAIK).

    I'll post some screenshots to demonstrate:

    a refresh of the page itself, produces different artifacts of the same nature:

    Sometimes, if you refresh a page enough times, you might not get these artifacts.

  • Round amount upwards or downwards by the numbers?

    I'm pretty new to numbers v3.6.2 so while I am very proud of my success with my effort first, very ambitious, I know I'll be defeated by a combination of the FI and around formulas. Then help with the following query gratefully received it please:

    I want to turn a series of cells upward or down to the nearest round number according to them being below or above the median.50.  IE: 16.34 becoming 16 and 16,79 become 17.  The cells can contain up to six figures (plus the two decimal points.)

    Please treat me as a novice and provide the complete formula!  Thank you very much.

    There is a function in figures aptly called "ROUND()" that takes two arguments:

    Round (number, places)

    num is the value to round

    places specifies how many digits to round

    assuming that the data is in cell A1, you can round the value as follows:

    = round (A1, 2)

  • Numbers rounded to a certain extent the price

    3.6.1 numbers question: I need help with a formula of round our price to xx.95 results. Where each product is an avec.95 price. I tried roundup and ceiling and cannot understand it. Thank you very much!

    Bill,

    Here is a simple solution that has a hole (in my opinion):

    column A contains the current prices and B contains the values "corrected".  From line 8, you can see that the prices are reduced by this method.  What is your intention?  You can share what you want the rule to the prices of the inputs between x.95 and x.99?

    the formula is:

    = INT (A1) + 0.95

    B1 = INT (A1) + 0.95

    This is the shortcut dethrone select cell B1 and type (tor copy and paste here) the formula:

    = INT (A1) + 0.95

    now select cell B1, copy

    Select cells B1 at the end of column B, paste

  • I continue to be offered an update of Firefox, but when I click on 'install' the bar just comes with half white, half blue round and does not install.

    I have a Macbook (bought in June 2011). Several times in recent weeks, I have been offered an update of Firefox and urged to install it.
    However when I click on OK the bar at the top of the window just goes round with the blue kind half white half of the roll and just install, no matter how long wait. That is, it never becomes the solid blue line, which should gradually fill to the top of the bar.
    Thank you
