• Determine if an integer is a floating-point number

  I want to create a program that when an integer is entered in the digital constant, a floating-point number with zeros to the right of the decimal point lights up the LED on the front panel. The LED remains off for any other floating-point number. I know I want to use a ride to the nearest function, but don't know where to go from there.

  You want to say CONTROL, right?

  You just need a type of rounding.  No matter if round you upwards or downwards.  If you just around and then compare the entry to the rounded value.  If they are equal, you turn on your LED.  So all you need is a digital control, 2 functions, and a boolean flag.

• BUG: Large floating point numbers convert the wrong integer

  Hello

  When you use the 'balls' conversion to convert integers to SGL, DBL and EXT there are certain values that convert evil. An example is the 9223370937343148030 integer that can be represented exactly as a SGL (and therefore exactly as DBL and EXT as well). If you convert this I64 you get 9223370937343148032 instead, even if the correct integer is in the range of an I64. There are many cases similar, all (I noticed) at the wide end of the ranges.

  It has nothing to with the integers can be represented exactly as a floating point value or not. This is a bug of authentic conversion you mind.

  See you soon,.

  Hi Steen,

  Thanks for this identification. I confirmed the EXT to U64 conversion problem in simply trying to make a round trip on a xFFFFFFFFFFFFF9B0 of value U64 EXT and back, is xFFFFFFFFFFFFFFFF as well (and the intermediate value in EXT is correct).

  The problem seems to be limited to integer values with the upper part of 53 bits set, as well as all of one or more of the 11 lowest.

  I have reported this (#396305), as well as the limited display accuracy questions (#396337).

• Convert c# to Java code - Floating Point Arithmetic

  Convert c# to Java code - Floating Point Arithmetic
  
  Hello
  I need to write a c# equivalent in java code. The c# code includes functions perform mathematical calculations. The result of these functions must match exactly with the c# (especially precision) counterpart. Here's a function that requires an equivalent java
  
  Public Shared Function squareroot (string n1)
  {
  If ((n1 == null) |) (System.Convert.ToDouble (N1) < 0))
  {return null ;}
  else {}
  return (Math.Sqrt (System.Convert.ToDouble (n1))) System.Convert.ToDecimal. ToString();
  }
  }
  
  C# two data types - float (32-bit) and double (64-bit) floating-point. It also includes a more specific data type float called decimal (128-bit). The float and double are supposed to follow the standard IEEE 754 floating point standard, but precise figures are different. Double c# has 15-16 digits for precision while the equivalent of java has 53, right? (the IEEE standard reference).
  
  Does anyone have an idea on what java equivalent data types/libraries must be used such that the results correspond with double c# and decimal?
  
  Thank you & happy new year

  This has nothing to do with the IEEE 754 standard, because nothing in IEEE 754 specifies how many decimal places should be used when a value is converted to a string. Simply because the resolution is between 15 and 16 decimal places does not mean that there is always an exact representation of any number of IEEE 754 format to 16 decimal places. In your example, Java chooses to create two decimal places more than c# don't but I bet that this is not a general rule you can count!

  The whole concept of using strings to represent the number seems to be skewed. I don't really see the point. It is mind bogglingly slow and in my view it does nothing for you. You have not yet met the real problem yet! What happens when Java or c# decides to use scientific notation?

  In your situation I would like to change the program c# use 'double' rather than 'chain', then you would find that you get an almost perfect match to all time. I make this recommendation of much written spending year of algorithms in C, C++, c# and Java of signal processing.

• floating point to hexadecimal string

  Hello

  Is attached a screenshot of what I'm trying to do.

  The equation that I in the formula box basically is supposed to enter a number between 30 and 100 (which represents the intensity percentage) and he will give a value in which when converted to the spell and fed in my instrument will give the corresponding intensity in floating-point (ie. 30% if I had entered 30 as my x in the formula) I need. Thus, for example my lowest intensity (30) would give me a decimal value of 239 of the formula which is "EF" in hexadecimal.

  This code does not work for some reason any. If I replace my conversion function of formula and hexadecimal, with only a simple chain control and display of spell and EF entry switch and feed it into the instrument intensity makes the adjustment to 30%! But I prefer to use the scale bar instead which does not... Can someone please tell me if my conversion function is messed up or something.

  Thank you!

• Decimal in Floating point with cookers

  Hello

  I am wanting to convert a decimal value to be implemented at the scale of a floating point value.

  For example.

  a decimal value from 0 to 20000 where half is considered to be the zero point. Then share values and on the other of this average value are considered postivie or double negative (0-10000 considered negative, 10001 to 20000 considered as positive). Then, the resolution of each decimal value is compared to a predefined scale.

  Don't know how to do in this regard.

  Any help is much appreciated.

  Hello

  I hope I got everything you wanted.

• floating points

  float f1 = 1f;
  float f2 - 1.00001f;
  System.out.println (F1 + F2);
  
  
  Will be the answer for this always be 2.00001? Or on different O/S will be there some time floating point math errors?
  
  Thank you

  Why is double used more frequently than the float for cacls. I thought that the two float and double are IEEE 754 float just has half the memory.

  Also probably errors in floating point mathematics are all the same if your use float or double?

  If I ask you to write a decimal number representing 1/3 through 8 digits, you would write
  0.33333333
  fix?

  And if I asked you to write using 16 digits, you would write
  0.3333333333333333
  fix?

  While it is closer to the real value of 1/3? And which one has the biggest mistake?

  So, now, if I ask you to represent 0.1 using a number in base 2 of 32 bits, and then to make using 64-bit, since we know there are infinitely many numbers to do, like 1/3 in base 10 which do you think will be closer to the real value and that there will be the biggest mistake?

• compare arrays of floating point

  Hi all

  I have a table of 2_D as

  1 0,0119

  2 0.0140

  3 0.0157

  up to 50 items.

  and the second picture is as

  0.0137

  0,0153

  0.0156

  up to 20 items.

  I need to compare second table with the second column that is the first table floating-point numbers . Find 20 items in table 1 that are as close as possible (maybe not exactly equal) to the 20 items listed in table 2.

  and return the corresponding values for the colors n ° 1 in table 1.

  ex. - 0.0137 will be compared with the entire table 2.

  He'll find 0.0140 and we get part 2.

  0,0153 next will be compared and so on.

  Final result will be a 1 d array with values of col 1 only.

  Help, please.

  It is confusing that name you the 2D file P1.txt and the 1 d P2.txt file.

  It seems simpler to use "worksheet file read" to read the two files.

  The mistake you make now is to create the table 1 d with the default tab as the delimiter. He reads only one, because there is no tabs in the file. All you need to is change the newline delimiter. It is what it is!

  

  Now, it seems to work perfectly, please test.

• floating point No. the chain with the same precision

  I use "format string" to convert floating point No. to a string. Most of the numbers have a single decimal digit, so I use '%^0.1f' in the format in the connection string. But for our whole. like 150, it gets converted to 150,0. I want to avoid this, such that the chain looks exactly like the No.... What should I change?

  Use %#0.1f as your format string.

  Read the help file on the format codes.  The sign # told him to truncate the zeros.

• Custom number Converter:-EL Expression

  Hi all

  I use JDeveloper 11.1.2.4.0.

  I have created a number converter to format number fields.

  I've referenced: Jerry on Java: create a custom converter of JSF 1.2 with the attributes and bunch of Red: tag JSP behavior customer personalized ADF Faces 11.1.1 Articles and created as a component of the taglib.

  I put the model to a numeric field based on a value of fields of wages as below

  #{bindings. Salary.inputValue gt 15000?' # 0.000 ': ' {# 0.00 "}".

  Salary is given as partial trigger deposited number and automatic sending is enabled in the salary field.

  I already pay value deposited. The loading of the page, the expression is used and the correct model is visible.

  But if I change the amount of salary not evaluates the expression and model does not change.

  But when refresh my browser tab then the model will change based on the new amount.

  For default converter I found the expression evaluates according to the change in the value of the wage.

  
  

  What I need to know is why EL Expression was not evaluated in the converter of custom number? I do any extra parameter?
  

  Please help me by providing some valuable links & Suggestions

  Thank you and best regards,

  Gijith

  Hi all

  Finally, I solved the problem of my custom number converter.

  It was that didn't save the handler class in the taglib.xml file. That's why expression evaluation works do not.

  After Manager class regitering everything works fine.

  Thank you dvohra21 for your reply.

  Kind regards

• Support for decimal and floating point in numbers

  Hi guys,.

  I use Illustrator (CC 2015.2 on Windows 10) in English in a country where it is common to use commas to separate the decimal and the holes of a number (rather than 5.11 5.11).

  I've often encountered the question as I enter the dimensions in floating points as 5,11 and Illustrator interprets as 511.

  
  

  Now, I know that other subjects on this forum depends on the locale and the language of my OS. I heard people from Sweden for example or other European countries running in this.

  
  

  But also, why doesn't Illustrator simply accept both commas and period as input in the fields?

  With the risk of underestimating the implementation, couldn't he just interpret my input string, fix the index of the comma and interpret the substring before the comma in the holes and the substring after it in decimal form?
