Javascript EA - calculate log() base 10?

• Series R FPGA, calculate log base 10 number > = 1

  Hi all

  I'm stuck on a problem with the calculation of a log base 10 of a number greater than 1.  It seems that natural logarithm in the high throughput math library is limited to the range of 1/1.  There must be others who need to work outside this range - how do we?

  Thank you

  George

  Hey gharris,.

  The only way I know to do this is through lookup tables.

  You want to probably use BlockRAM and use VI initialization, as described here. You also have a table of logarithms, which covers the range that you expect to encounter. For values outside of your table, you'll need to interpolate.

  To get this right for your application may take a bit of tweaking, especially if you have a tight deadline or a need for high precision.

• Calculation of log base 2 of 35 s new

  I would like to calculate the necessary resolution for an ADC with analog input will accept a +/-10V swing with a background noise of 0.4mV. The counties of RMS are 20.0V/0.0004V = 50 000 points - just easy. To set the 50 000 RMS number of bits is: bits = log2 (50,000). How can I make my new imagination 35 s to calculate log base 2 of 50 000? Help is appreciated - thanks.

  Hello

  To calculate LOG2(A) use LOG (A) / log (2) or LN (A) /LN (2).

  Here is a program to do this (run in RPN mode):

  

  To use, type number and XEQ, then, ENTERED.

• JavaScript to calculate a field value

  Hello world
  
  I'm trying to write a small javascript to calculate a value in field based on another field value, similar to Denes Kubicek example on the next page:
  
  http://HTMLDB.Oracle.com/pls/OTN/f?p=31517:71:3928458344147956:no
  
  My model is:
  
  Champ_1 (source of calculation). Champ_2 (calculated value)
  
  The calculation is as follows:
  
  Champ_1 X 2 = Champ_2
  
  Of course, I'm a newbie to JavaScript, but I need help.
  
  Thanks in advance for your advice!
  
  Charles

  Hello Charles,

  Depending on the number you use you must don't like Dene fact (use of tank and getVal Parse).
  But that would be a very simple example: $x.value ('P1_FIELD2') = $v ('P1_FIELD1') * 2;

  Kind regards

• JavaScript to calculate the DEPOSITS REGULAR CALCULATOR

  Looking for a JavaScript calculator that calculates compound interest results with a base amount, annual interest rate (which allows the user to calculate monthly or annually), set the period of calculation, regular monthly deposit and interest rates. The user would have the opportunity to increase the annual deposits with Inflation and change compound monthly or annual interval.

  That is to say

  Basic amount: $30,000

  Annual interest rate: 3%

  Calculation period: 10 years

  Regular monthly deposit: $200

  Inflation rate: 3%

  Increase deposits annually with Inflation or not

• JavaScript to calculate the average of a column

  I have my PDF file I'm trying to calculate the average in a column of fields.

  My problem is that there are 7 areas, but all 7 can be omitted, so I think I need some sort of statement 'if' that would only count the number of fields containing values.  Then, somehow working in the rest of my calculation...

  That's what I have so far...

  (function () {}

  Get all the field values, as numbers
  var v1 = + getField("column.0").value;
  var v2 = + getField("column.1").value;

  var v3 = + getField("column.2").value;

  var v4 = + getField("column.3").value;

  V5 var = + getField("column.4").value;

  var V6 = + getField("column.5").value;

  v7 var = + getField("column.6").value;

  var V8 = + getField("column.7").value;
  
  Calculate the result and the value of this field
  Event.Value = (v1 + v2 + v3 + v4 + v5 + v6 + v7) / the number of fields that have been filled;

  })();

  I'm pretty new to javascript. Any help would be greatly appreciated! Thank you

  First of all, I woul write this function withou field reference to make it more universal, and then I have a funcion of document level so it could be used more than once in a PDF document and easily put into another PDF file.

  function Avg() {}
  average computer of the last non-empty field names
  var sum = 0; sum of the fields
  var number = 0; meter for non-empty fields
  for (i = 0; i< arguments.length;="" i++)="">
  iField var = arguments [i]; get the element of arguments passed
  var fField = this.getField(arguments[i]).value;
  If (!) isNaN (fField)))) {}
  field is a number
  If (fField.ToString ()! = ") {}
  field is not null or empty
  sum += Number (fField); Add to the sum
  Count ++; County of increment
  } / / do not blank end
  } / / end of number
  } / / end of loop iterative arguments
  If (count! = 0) {}
  calculate the average if there is one or more items on average
  to return the sum / count; Returns the average
  } else {}
  return ";
  } / / no end no average calculated
  } / / end of function Avg

  Your custom calculation script would then become:

  Event.Value = Avg ("column. 0', 'column.1', 'column.2', 'column.3', 'column.4', 'column.5', 'column.6', 'column.7');

• The use of Javascript to calculate monthly payments on form

  I have a form one page where I want to be able to allow the user to choose between making a time payment or monthly payments for an amount defined by the user. I could easily penetrate the shape of two pages and calculate the value of monthly payments and post it on the second page, if the user has selected the monthly payment option. What I would like is a single page where the monthly payment is determined on the fly when the user selects the box of monthly payment option or the user defined amount is entered.
  
  I think I have the function determined to do the calculation for the monthly payment, but I'm not sure how to get CF to read or display the value. I tried to use the following with no luck:
  
  < input type = radio name = value of payments = "Yes" tabindex = 1 onClick = "calculatemonthlypayment (return [0].). DonationAmount) ">"
  
  < script type = "text/javascript" >
  function calculatemonthlypayment (donation)
  {
  monthlypayment =(donation/12)
  }
  return monthlypayment
  < /script >
  
  You try the result like this:
  
  < cfoutput > < input type = "text" readonly = "yes" value = "#dollarformat (monthlypayment) #" > < / cfoutput >
  
  No idea I'm doing wrong or missing? Or is there a better way to do this?

  >

  You can't do that. CF code runs on the server (the first). The javascript that results (html, css,...) is sent to the browser where it is running. Given that the javascript code is executed in the client browser, after the CF code is already completed, the variable "monthlypayment" does not exist that CF is concerned.

  You can use javascript to read the amount of the donation text field and calculate the amount of "monthlypayment" to display. Here's a simple example. You will need to add validation and formatting number.

• calculate the base on a mc on a mc

  Hey people,

  I have a running total. When a mc hits the table or hand it will adjust the total. The problem is that I want only the total in order to take into account when an object is placed on the mc of the hand. If I remove something from him, delete its value altogether. Now to be smart I have add when a mc hits the hand and remove a value if a mc hits the table. The problem, if I never touch the hand and continue to drop the mcs on the table, I get a negative value. Is there a way to calculate a total only when a mc is based on the mc of the hand and remove the appropriate otherwise value on that?

  This error does not seem to relate to your metering code.  It indicates that a function you have expects an argument to be passed to it, and no argument is passed.  Go to your publication settings and select the option to enable debugging.  The messade of error can then include the line number where the problem arises.

• Apply the condition on the page to allow access if Javascript is enabled

  Hi, is there a way I can put a condition on the page to allow access allow access only if java script is enabled?

  I have a heavy use of Javascript to calculate different values in a page and want to ensure that if Javascript is not enabled in the browser they do not get to use the page.

  APEX is JavaScript-dependent, it is unlikely that users will even be able to log in and access this page, unless you already take steps throughout the application to allow it to work with JS disabled.

  Also note that for security reasons all depends on the JS in the browser must be verified on the server when the page is sent.

  Whenever you have a problem with a built-in function, check the Manual of the SQL language to know if you uisng it correctly. I find certain features not intuitive.

  I used this

  
  select log(0.33,2) from dual;
  

  The first argument of JOURNAL is the basis. I think you have the opposite arguments.

  the results that showe me is

  -0.62521
  

  but the correct answer is

  -1.58
  

  Do you mean - 1.5994621...? (Remember,.33 is not quite equal to 1/3).

  y at - it an idea.

  Try

  LOG (2, .33)
  

  or

  LOG (2, 1/3)

  Hi Steve,.

  There are some errors in your code.

  1. function 'getmyDoc' is used, but not created.
  2. fucntion 'getScriptPath' is created but not used. (In any case, this will not give you error)

• using toFixed in javascript in a table

  Hi all
  
  I have a tabular presentation in a javascript on a column calculation.
  

  Column 9 = column 5 * column 7 

  See below (onchange) javascript code:
  

  <script language="JavaScript" type="text/javascript">
  <!--
  function calcit(pThis)
  {
  var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);
  
  
  document.getElementById('f09_'+vRow).value = document.getElementById('f05_'+vRow).value* document.getElementById('f07_'+vRow).value;
  
  
  }
  //-->
  </script>

  The columns are number 5,234.10 format
  
  Now, users have the abbilty to enter number like 5,234.10455 etc.
  The calculation is then made out based on what the user has entered.
  But I want the calculation is made according to 2 decimal places (as the specified number format).
  
  I read that this can be done with toFixed.
  Where in my code should I put the toFixed?
  I tried to put it like this document.getElementById('f07_'+vRow).value.toFixed (2), but then my javascript calculation calculates is no longer.
  
  I could really grateful for the help on this.
  
  Thank you

  Try to use: parseFloat (document.getElementById('f07_'+vRow).value) .toFixed (2)
