Is it possible to convert a float to two decimal places

Can anyone help me to convert a float to two decimal places
float f=16;
System.out.println(f);
It will print 16.0
But I want to get printed as 16.00

"convert" no, as no conversion is needed, obviously. Format the output, yes. Read the API for String and its printf method.

Rounding off a float to two decimal places

I want to make a function where I shall pass a float and and integer.
The float shall have to be rounded off to a value in the integer.
Can anyone please suggest how to round off a float.
E.g.: if the float is 12.56890 and I want to round it off to 2 decimal places, then it should be 12.57.
Regards
Hawker

I didn't mention any datatypes like float, double.True, but that is what the question is about, so you weren't answering the question. For a change.
As I mentioned, that was just a mathematical steps to round of the floating point value. (Not in any programming languages point of view).False. You didn't mention that at all.
This is the code for that in java.So here you are mentioning datatypes and floats for the same piece of mathematics that you have already been told, with reasons, doesn't work in floating point.
which seems to be working fine
Seems to. What evidence do you have that the float actually got rounded? As opposed to got displayed as rounded? Which is not what the OP asked for.
And of course all that code seems to do is round 0.01 to two decimal places, which again is not what the OP asked for.
For any remaining fans of this 'technique', please explain the behaviour of the following code:
     public static void     main(String[] args)
          int     count = 0, errors = 0;
          for (double x = 0.0; x < 1; x += 0.0001)
               count++;
               double     d = x;
               int     scale = 2;
               double     factor = Math.pow(10, scale);
               d = Math.round(d*factor)/factor;
               if ((d % 0.01) != 0.0) // if 'd' really has been rounded this should be zero
                    System.out.println(d % 0.01);
                    errors++;
          System.out.println(count+" trials "+errors+" errors");
     }

Convert rounded number into two decimal places

Hi All,
I have a Number 156 stired in a column having number(10,2);
but i want to update it into 156.00......
May be simple,,,,but how?
Edited by: 887268 on May 29, 2012 10:04 AM

Hi,
156
156.00
156.0000000000000 and
00000156.0000 are all the same NUMBER. There's nothing to convert.
If you want to display a NUMBER in a certain way (e.g., with 2 digits after the decimal point) then use TO_CHAR, or have your front end format the column. In SQL*Plus, for example, you can use the COLUMN command:
COLUMN   sal     FORMAT 99999.99
SELECT ename
,       sal
FROM    scott.emp
;Output:
ENAME            SAL
SMITH         800.00
ALLEN        1600.00
WARD         1250.00
JONES        2975.00

Storeing values in floate data type upto two decimal places

Hi
I want a float type field in my table but want to store value up to two decimal places.
so what syntax i need to follow plz suggest.
thanks

it is not possible to store with Number datatype. if you are using the data to sho report, then change its format (like 45 to 45.00). if you want to store 45.00 in database, then you have to modify the datatype for that column. for this follow the following path
1. Add a column of datatype Varchar2.
2. Copy all the value of your number field to it.
3. Drop the old column.
4. However make sure that if you have used that column somewhare in arithmetic calculation, the modify it and use to_number function to do arithmetic opration.

How to take float precision to two decimal places?

Hi, everybody:
I'm a straight noob...first week in Java programming. Before you bash me for not checking FAQs and such, believe me, I have.
I have tried BigDecimal movePointLeft, but I don't know how to construct it using proper syntax. I also tried currency and toString but I keep messing up my syntax somehow. Four hours into this and nothing is working.
Here is the problem: I have a float. I want to format its output to two decimal places, trying to achieve in Java what C would produce as:
printf("The amount you owe is $%.2f", fltAnyName);
Any help would be appreciated.
Thanks,
Rob

Sorry, guys. I have tried both recommendations and I can't get either to work. I'm getting a compile error pointing to the delineating period between the "out" and "printf" when I try the C-like code. I have 1.5, too. I know your advice is sound so I must be doing something wrong. Can you insert the code DecimalFormat code that will correct this problem where it needs to go? The packages below have been included becasue of all the different solutions I have attempted.

Convert to two decimal places

Hi I have some code which I have written but am unable to convert it to two decimal places. Have tried various techniques by looking through some of the forums. My problem is that my data starts off as varchar(500) and initially I have to substring to get
the actual numeric part of the data.
At the moment i get a result such as 48487.800000. I would like 48487.80.
Just wondering if anyone has any ideas where I could be going wrong. Here is my effort.
select SUM(Next_Value)/100 AS ResultExpected from
Select A.ID, A.LogData,
(Select Top 1
--CONVERT(numeric,
-- cast(substring(B.LogData,6,36) AS numeric(10,2))
--CONVERT(numeric(8,2),cast(substring(B.LogData,6,36) as numeric(8,2)) )
cast(substring(B.LogData,6,36) as numeric(10,2))
From HMRC_Load B
Where B.Id > A.Id and A.LogData like 'NewFigure%'
order By B.Id) as Next_Value
From HMRC_Load A
where A.LogData like 'NewFigure'
) AS ResultExpected

Rounding off float to 2 decimal places and returning the float

I tried doing bigdecimal but it doesnt work. :
BigDecimal bd = new BigDecimal(5 * 0.0394);
          retval = bd.floatValue();
          System.out.printf(" th %f\n",retval);
I see 0.197000. I know that there are 6 places since I didnt do %.2f. However its not the printf thats important . The float I want to return must be rounded off to two decimal places.
Thanks in advance for the help,
sb

Use BigDecimal.round( MathContext mc ), where the MathContext object is set to a precision value of 3;
BigDecimal roundedBigD = myOriginalBigD.round( new MathContext( 3 ) );� {�

Round float to 2 decimal place in the table

Hi,
One field in a table in my DB has float datatype.
I insert some data into this table. The value read from a textbox I input as 0.02 for example. after insertion, I select the table and the field of the table shows the number as 0.0199999995529652
Where did I do a wrong thing? how can I make it exactly as 0.02 in the table?
Thanks.

Hi there
Float data types have known problems with precision, see
here
Since FLOAT and REAL are approximate numbers, you can run into all kinds of presentation / storage issues if you use them inadvertently.
They have their place, and if you are using scientific data that requires the properties of floating point numbers, th they are the right choice. But in most cases, I think this is another evolutionary thing that happens accidentally when you upsize
from Access. You are much better off using DECIMAL or NUMERIC (which are functionally equivalent) unless you really know that you should be using FLOAT.
You should consider changing the datatype to decimal or numeric if you need it to be more precise.

Convert amount with four decimal places to amount with two decimal places

Hi,
for specific reasons we have set the prices to four decimal places. However, in an invoice the staff needs to see all prices with two decimal places. Therefore I have created new user-defined fields which should show the rounded values However, I have not yet found the right formatted search that outputs the value with two decimal places including currency symbol.
The statement
SELECT $[$38.20.NUMBER]
outputs the value with two decimal places which is fine, but it does not contain the currency.
The statement
SELECT $[$38.20.0]
outputs both value and currency, but the value still has four decimal places as the original price.
And the statement
SELECT CAST($[$38.20.NUMBER] AS VARCHAR(20)) + $[$38.20.CURRENCY]
outputs a value with even six decimal places.
Did anyone already have the same problem???
Or does anyone have any idea???
Thanks and regards
Corinna

Hi again,
the value should be displayed in a user-defined field of the screen.
The result of the query
SELECT $[$38.20.NUMBER]
has already two decimal places, so that I do not need a round here. But the currency is missing.
When I add the round function to the query
SELECT $[$38.20.0]
it does unfortunatly result in an error.
Any ideas????
Thanks so much in advance!

I would like to convert a float to integer..........

First of all, avoid my previous question.
Secondly, i would like to have an output in my program float numbers but until one decimal . for example 23.5 56.8 23.8
How can I do that.I know there is a rounding method but a number like 23.546935609 it will be 24. I do not want that.
For understanding my program ,it is read a number as a command argument ,so string, i converted as a float for taking : 23,7 but i do not want to take from the command line 23,98765544........it is too big for my job.
Any suggestions?Can i use try catch commands for this?

Also, if you'd just like to format the output, you can use the printf() method.
i.e.
public class Test {
     public static void main(String[] argv) {
          float g = 1.234567890F;
          System.out.printf("To one decimal place: %.1f\n", g);
          System.out.printf("To two decimal places: %.2f\n", g);
}

Is it possible to convert an app from 12c to 11g?

I am using both 11.1.2.4 and 12.1.2.0.
If I have an app built with 12.1.2.0, which does not include any 12c specific features, is it possible to convert it to 11.1.2.4?
I am asking because I have a Development environment that is 12c, but a Production environment that is 11g and I am not sure we will be able to upgrade the Production environment
Thanks in advance..

It's possible but not an easy task. As 12c uses newer stuff you have to test everything with great care. You might find some things you have to rebuild add they won't work in 11.1.2.4.0 (e.g. components which are only available in 12c. If you read the what's new doc for 12c and you find something you have used, prepare to rebuild this part.
First thing to try ids to open the project in 11.1.2.4.0 and see if you can compile and run the app.

Is it possible to convert text captions to Smart Shapes?

Hello,
I have a collegue that is using Cp 5 to record software simulations which then need to be brought into Cp6. The problem is that our standards (for software simulations) employ Smart Shape call outs (not the Cp 5.5 and earlier text captions).
Is it possible to convert these text captions into our themed Smart Shapes either automatically inside Captivate 6 or by modifying the content within the CPTx file?
Thank you,
Shawn

Hello Lilybiri,
As always you are awesome! :-)
>I don't believe an automatic switch will be possible, because smart shapes are totally different objects.
I understand because there are a huge variety of shapes in either format. But I suspect that it should be easy to convert a text caption from any style to one specified smart shape style.
Actually, I am asking before the simulations get started. So nothing has been done yet. I am unsure what you are suggesting I should do in the preferences under Cp 5.5. Are you suggesting that there is a way to convert 'some format' of text callouts, in a Cp5.5 demonstration simulation, to Smart Shapes in Cp6?
>but since you already have created the simulations, it has to be done manually. Hoping for you that
>someone has a bright idea, but I do not see one immediately.
For anyone else in this situation, it would be handy to have a solution (rather than painstakingly convert each manually).
I am wondering if this might be a relatively easy search/replace within one of the xml files within the CPTx file. I'm going to look at this tonight.
Thanks for your assist.

Dear friends
Is it possible to convert PDF file into HTML. I have few hundread PDF files i like to convert this files into HTML. I hope it can be done through Java but i don't know how to start this coding. anybody can give me a brief idea to go ahead.
