string to a rounded decimal number question

• Readed hexadecimal string converted to a decimal number.

  Hello! I do a vi to check the hours of the lamp of my Sony projector. I send a hexadecimal command which is: A901 dignitaries 1301 0000 139 a senators. When the projector receives answer with 1901 1302 0031 339. 0031 corresponds to the data that I need to convert it to decimal because it tells me how many hours we used the lamp. How can I get this read-separated string to get only the third part of hexadecimal numbers converted to decimal? Thanks in advance!

  Hey rounded!

  As the data is in a format string, the hexadecimal number VI string should work well in this case.

  To enter only a single figure of this string to use in the hexadecimal number string VI, then I suggest using the string subset VI; Returns a specified segment of a string. By changing the offset of entry which determines which part of the string data is beginning to be analyzed from and changing the length to control the amount of characters to analyze, you will be able to enter the character that you want to convert.

  Kind regards

• How to round a number to a specific value and not to a certain number of decimal places

  Hello

  I'd round up the numbers according to a grid.

  Let's say I have a grid of 6 between 3 and 4 (3.0 3.2 3.4 3.6 3.8 4.0)

  I'd round up to the nearest number in the grid, so if I choose 3.7125, it will turn to 3.8.

  I found already in the forum how to round decimal degree, but not in my approach.

  You know to force rounding to the nearest of the grid.

  I thought a ramp up to make the grid then interpolate the number and use its index to round. But I don't know that there is a much easier way.

  Thank you

  These ideas, everything seems to work if you try to round up to a set of specific values.  But you must set specific values for all the possibilities.

  If you want to round to a given interval, there is an easier way to do it.

  If you want to round each 0.2.  Divide your number of this interval.  Round to the nearest integer.  Multiply your number of this interval.

  

  If you need to force a number less than or greater than a given to be in this range, such as having range 1.255 round up to 3, then put a stove and Coerce before or after this piece of code.

• Convert a decimal number to a string

  I work with a gas mixer and I try to transmit data rates. The mixer takes only decimal values, for example, if you want to 2500 cc debit you must pass it 2500.0. I tried to use the function of decimal string number and do a type cast but I get an error every time machine. The only thing that works is by using a control of the chain and entering the value, but I would like to do it with a digital command. Someone at - it tips or advice?

  

  Note that you have provided only a sample size. In addition, 2500.0 isn't a decimal number, it is a floating point value.

  It is also not clear if how you talk to the machine. You said that you used a Type Cast. For what? How do you communicate with the machine?

• Result of the calculation were separated to the whole and decimal, number not rounding correctly

  I have 2 fields as a result of sharing: the whole and decimal number (1 decimal place). I Math.floor the result to get the whole number and everything is fine until I hit a case where the result is 92,97.

  This should give "93" in the whole of the field and '0' in the decimal field, instead it gives me '92' and '10' (even though I'm only hosting 1 character in the field).

  How can I get the '93' and '0' in the following code?

  fieldLVEDV = this.getField("LVEDV").value;

  fieldBSA = this.getField("BSA").value;

  If (fieldLVEDV! = "" & & fieldBSA! = "") {}

  totalLVEDV = this.getField("LVEDV").value + ((this.getField("LVEDVDec").value)/10);

  calculation = (totalLVEDV / fieldBSA);

  calculationDecimal = calculation;

  partWhole = Math.floor (calculation);

  if(partWhole <0) {partWhole =' ' ;}}

  this.getField("Index").value = partWhole;

  this.getField("IndexDecimal").value = Math.round (10 *(calculationDecimal-partWhole));

  {If (this.getField("IndexDecimal").value = '10')

  {

  this.getField("Index").value = partWhole + 1;

  this.getField("IndexDecimal").value = "0".

  }}

  } else {}

  this.getField("Index").value = "";

  this.getField("IndexDecimal").value = "";

  }

  I thought I'd add the blue part would do the job, but obviously it did not work.

  Ah, your problem is that you do not use the correct comparison operator. To check if two values are equal, the operator is "==" not not "=". Using "=", you assign the value 10 to the field which you then pass in 0 a few lines down. Use 'is' and things should work correctly.

• Rounded at most about base 2 "set decimal number."

  If I get the decimal number 121, I want to turn that to 128. If 513, I want to round up to 512. If given 48, I would round which is for 32 or 64 (I fear particularly that!).
  
  The key is for all decimal entry, I want to limit the return to the 1,2,4,8,16,32,64,128,256,512 and so on '2 powers of base' (i.e., 2 ^ n)
  
  The ROUND function does not, at least as much as I know. Are there any other built-in function to do? Or a single SQL statement that allows to get the same?

  A basic idea...

  select power(2, round(log(2, :x)) ) from dual

• generate the signal of decimal number

  Hello

  I have a program that calculate the heart rate from the ECG signal. I want to show the beats per minute on a graph with 60 s of the plot of the story.

  Since the vi who calculate the heartbeat I get output the string with the number, only when the wave of the tip, then I convert it to a number and then I place the offset of a simulated DC signal.

  (In the table below the beats per minute are always 60 because I'm simulating a sinusoidal signal with 1 Hz).

  ------>

  It works fine, but I'd like to see not the summits but a continuous line from one point to another, such as interpolation.

  in this case, it would have been a horizontal line to 60 BPM.

  I thought to store the last value of the chain and keep it frozen until the next update of value.

  Do you have suggestions on how to do it?

  Concerning

  Not clear what you get in the form of numbers, seems that you get too many zeros, and you get a decimal number or another 'dynamic '? value?

  You pulse-rate information could be ~ 45 to > 180 values per minute!

  You display the exact story of a minute?  Maybe (keep the last ~ 300 values with timestamps and use an XY diagram) a graphic story can be configured to display

  wait... Here's one way:

  I fed a chart (with 256 points in history), with a waveform. the wfrm has only a single value in the array of values and a t0. The chart is configured to display the 60 sec.  Seems to work

  My simulation will display a min rate of ~ 45 BPM, but you can beat him

  

• Displays the decimal number

  Dear All;
  
  I just want to get a decimal number (i.e. 2.5), I tried the mathematical functions, it has not solved the problem.
  Is there another function that returns a decimal numbers. ?
  
  
  Thank you;

  In the case where what you mean is you have found values in the path of 2.66666667, etc. and want to round down to 2.7, that can be performed as follows:

  var pH:Number=Math.round(140*(-ySlider/550)) / 10;

  Essentially, you multiply the value by 10, round, then divide by 10.

  Hello OzShimon,

  It's weird, I just tried your code and get this result:

  

  I noticed that this behavior can be changed in the configuration "Regions and languages" of Windows. In Windows 7, it's this dialog box:

  

  If I change the settings of this dialog to any of the zeros, the result is the same as you have described.

  Can you check your Windows settings and confirm that yours looks the same as mine?

• How to test if the rest is a decimal number or an integer?

  Hi guys!

  I want to check whether or not my rest of two integers is a decimal number. Also, if it is a decimal number, I wana it allows to do a thing and if its an integer, I want her to do something else. How can I do?

  Help, please!

  Thanks in advance.

  The task is to divide two numbers X and Y and a LED lights up if the result/rest is a decimal number. It can be higher or lower than 1, is not serious. If it is not a whole number, the LED should light.

  Great looks that you know exactly what you want to do, which seems to be the problem?  You will find the functions you need in the digital, boolean and comparison scheme.

• Enter a decimal number

  I'm having a problem of construction of the line "input" to ensure that the user can enter an integer or decimal number in form-> table cell, but not all the other characters.

  When I use the type = "number" as below, the user can enter a decimal places but gets a warning 'only an integer' to submit.

  Thanks for any help.

  The default step for an input number element value is 1. To allow decimal values to be entered into a numeric field, you can assign the step attribute to "any" or a decimal value.
