How to input a number of scientific notation in equations

On new version of Numbers, I try to input a equation, such as "=A1 x 6.02E+23" , but I cannot input the equation, because "E" regarded as "columnE".
Please tell me how to imput a a number of scientific notation in equations.

You can override the parser using escape. This might be new to version 3.2, I don't remember it in 3.0 or 3.1. It used to override it until you hit Enter, then it would revert back into a cell reference. Now it is working correctly.
= A1*6.02E (then hit ESC) 23
The result will be
=A1×6.02E+23

External table.How to load numbers (decimal and scientific notation format)

Hi all, I need to load inside an external table records that contain 7 fields. The last field is called AMOUNT and it's represented in some records with the decimal format, in others records with the scientific notation format as, for example, below:
CY001_STATU;2009;Jan;11220020GR;'03900;CYZ900;-9,99999999839929e-03
CY001_STATU;2009;Jan;11200100;'60800;CYZ900;41380,77
The External table's script is the following:
CREATE TABLE HYP_DATA
COUNTRY VARCHAR2(50 BYTE),
YEAR VARCHAR2(20 BYTE),
PERIOD VARCHAR2(20 BYTE),
ACCOUNT VARCHAR2(50 BYTE),
DEPT VARCHAR2(20 BYTE),
ACTIVITY_LOC VARCHAR2(20 BYTE),
AMOUNT VARCHAR2(50 BYTE)
ORGANIZATION EXTERNAL
( TYPE ORACLE_LOADER
DEFAULT DIRECTORY HYP_DATA_DIR
ACCESS PARAMETERS
( RECORDS DELIMITED BY NEWLINE
BADFILE 'HYP_BAD_DIR':'HYP_LOAD.bad'
DISCARDFILE 'HYP_DISCARD_DIR':'HYP_LOAD.dsc'
LOGFILE 'HYP_LOG_DIR':'HYP_LOAD.log'
SKIP 0
FIELDS TERMINATED BY ";"
MISSING FIELD VALUES ARE NULL
REJECT ROWS WITH ALL NULL FIELDS
"COUNTRY" Char,
"YEAR" Char,
"PERIOD" Char,
"ACCOUNT" Char,
"DEPT" Char,
"ACTIVITY_LOC" Char,
"AMOUNT" Char
LOCATION (HYP_DATA_DIR:'Total.txt')
REJECT LIMIT UNLIMITED
NOPARALLEL
NOMONITORING;
If, for the field AMOUNT I use the datatype VARCHAR (as above), the table is loaded but I have some records rejected, and all these records contain the last field AMOUNT with the scientific notation as:
CY001_STATU;2009;Jan;11220020GR;'03900;CYZ900;-9,99999999839929e-03
CY001_STATU;2009;Feb;11220020GR;'03900;CYZ900;-9,99999999839929e-03
CY001_STATU;2009;Mar;11220020GR;'03900;CYZ900;-9,99999999839929e-03
CY001_STATU;2009;Dec;11220020GR;'03900;CYZ900;-9,99999999839929e-03
All the others records with a decimal AMOUNT are loaded correctly.
So, my problem is that I NEED to load all the records (with the decimal and the scientific notation format) together (without records rejected), but I don't know which datatype I have to use for the AMOUNT field....
Anybody has any idea ???
Any help would be appreciated
Thanks in advance
Alex

@OP,
What version of Oracle are you using?
Just cut'n'paste of you script and example woked FINE for me.
however my quation is... An external table will LOAD all data or none at all. How are you validating/concluding that...
I have some records rejected, and all these records contain the last field AMOUNT with the scientific notation

Create an NSString for number in scientific notation from double?

Hi
Given a double, I want to create a string in scientific notation.
e.g for a double with a value of 123.456, I want the NSString to be "1.23456e+2" for entering in to a UITextField.
I've looked through the docs but can't find a formatter. (There is mention of "%a" being scientific format, but it produces hex output.)
Thanks for any clues.
Steve

Is there some place where I can submit a ticket ? Seems like FF limits DOM elements' width and height to 10,000,000px since it transforms this number into scientific notation. e.g. 10,000,000px becomes 1e+7px which obviously can't be interpreted. Cheers

I've reproduced this issue from FF 3.6.13 on windows XP and mac osx 10.6.8.
On FF 3.6.13 the number of pixels limit seems lower with exactly 8,388,607.

The 12" PB internals are a bit more complex, for PB's. If you don't want to replace the hard drive yourself or pay someone to install it, you could always get an external firewire hard drive, and use it to boot from and for general usage. Would have to be firewire, since the PB won't book from a USB device. One example of what you could get is a 160GB external hard drive: http://eshop.macsales.com/item/Other%20World%20Computing/MS4U5160GB8/ . All the choices with that case are listed here: http://eshop.macsales.com/shop/firewire/on-the-go
Have you called any Apple Authorized Service Providers to see what they would charge to install a drive for you? Whether you bought it or they supplied it? You can find a local one in the US at http://www.apple.com/buy/locator/service/

Long number in CSV file appearing in scientific notation by default

Hi,
How can I stop a long number in a CSV file that is opened in excel from appearing in scientific notation by default?
eg.
"hello","778002405501 ", "yes"
becomes:
hello | 7.78002E+11 | yes
I have tried wrapping the data in quotes in the csv but to no avail.
Thanks in advance,
Alistair

You can change the extension from ".csv" to ".xls" and use table to form the data and use
style=”mso-number-format:\@;”
Please read the sample code below in Classic ASP:

Calculator.app Version 4.5.3 (99.2) and Scientific Notation

I want to enter a number with scientific notation.
2.71e1 doesn't return 27.1, but rather 0.999...
It seems that Calculator.app is dividing by e.
This is not a common operation.
2.71E1 gives 27.1great! But ...
2.71E-1 does not return 0.271 neither does
2.71E(-1)
I have yet to figure out how to use negative exponents in Scientific notation.
This seems to be a bug in Calculator.app Version 4.5.3 (99.2)

All my spaces were deleted.
Take two.
My input ======= Calculator
2 ============ 2
2. ============ 2.
2.7 =========== 2.7
2.7E ========== 2.7 E 0
2.7E- ========== 2.7 (and the small - subscript indicating a negative number)
2.7E-1 ========= 1 (and the small - subscript indicating a negative number)
Now hitting enter === 1.7 (it appears to have subtracted 1 from 2.7)
Do our version of Calculator match?
Thanks for being interested.

Decimal Format and Scientific Notation

I am trying to print numbers in scientific notation using the Decimal Format class. What follows is a simple test program I wrote to find the bug. So far, I have not found a solution.
import java.text.*;
public class formatted {
public static void main (String Arguments[]) {
DecimalFormat form = new DecimalFormat("0.###E0");
double numb = 123456.789;
System.out.println("Nuber is: " +
form.format(numb));
The output of this program is... Nuber is: 123456E
The output is the same if numb is an int, float, or double. If I format the number as "#####.0" or "#####.00" the output is correct. I think that I am following the rules for formatting a number in scientific notation as the process is outlined in the documentation (provided below).
***** From Decimal Format under Scientific Notation ***
Numbers in scientific notation are expressed as the product of a mantissa and a power of ten, for
example, 1234 can be expressed as 1.234 x 10^3. The mantissa is often in the range 1.0 <= x < 10.0,
but it need not be. DecimalFormat can be instructed to format and parse scientific notation only via a
pattern; there is currently no factory method that creates a scientific notation format. In a pattern,
the exponent character immediately followed by one or more digit characters indicates scientific
notation. Example: "0.###E0" formats the number 1234 as "1.234E3".
Anyone understand how the short program is incorrectly written?
Marc

The problem is
format = "0.###E0"
input number = 123456.789
output = 123456E (not scientific notation!)
This is not scientific notation at all. There is no decimal point given and no value in the exponent.
I understand entirely that by adding more #'es will provide more precision. The bug I have is the output is not printed in the scientific format; other formats work.

To_number and scientific notation

Hi
I am trying to convert a number in scientific notation stored in a character ffield to a number.
I use this statement, but gets a ORA-01722 error.
What is wrong ?
select to_number('1.1111111111111112E-6','9.9EEEE')
from dual
Preben

Hi guys, I'm following this forum in order to reuse what you wrote, but I still have a problem with the scientific notation format...
From SQL Plus If I run this query:
select b.CONTRACT_NUMBER,b.id as cont_id from OKC_K_HEADERS_B b--, okc_k_lines_b v
where b.contract_number = 'NR19Mini'
I retrieve the following row:
CONTRACT_NUMBER CONT_ID
NR19Mini 1.4733E+38where the CONT_ID datatype is NUMBER.
Now I want to specify a condition using the CONT_ID field (for another use in the future), but if I use the following syntax
select b.CONTRACT_NUMBER,b.id as cont_id from OKC_K_HEADERS_B b
where b.contract_number = 'NR19Mini'
and b.id = to_number('1.4733E+38','9.99999EEEE');
I don't retrieve any rows (no rows selected)
How can I modify the format number in order to see my row, and for example use it inside a join with another fied of the same type ?
Thanks in advance

Formating scientific notation

Hi,
I'm working with a small program where at one point a number, in scientific notation will need to be formated into a string containing plane numbers.
I use the code below, and it works in up to large numbers where the formatting doesen't do aything at all.
String InputValue = "7,584995286E7";
NumberFormat format = NumberFormat.getNumberInstance();
Number number = format.parse(InputValue);
String OutputValue = number.toString();
System.out.println(OutputValue);The example above gives the result input back as output value: 7.584995286E7
With the value 7,584995286E6 the result is: 7584995.286 just as I want it to work.
What can I do to solve this?
All help is appreciated.
Thanks
/H�kan

Hi ,
Below is the code posted by you.
String InputValue = "7,584995286E7";
NumberFormat format = NumberFormat.getNumberInstance();
Number number = format.parse(InputValue);
String OutputValue = number.toString();
System.out.println(OutputValue);Add these two methods, and you will get the code working as you needed.
format .setMaximumFractionDigits(3)
format .setMinimumFractionDigits(3);

DecimalFormat scientific notation if necessary

I would like to find a way to output a double value in a way that uses scientific notation only if the number of digits output would be at least 15. For instance, the value 12345000000000000 should be output as 1.2345E16, but 12345000 would not be output in scientific notation (and the same logic if the value is < 0). Is this possible with the DecimalFormat class?
I tried using String.format("%.15g", value), but that always displays trailing 0s to fill the significant digits (e.g. 12.345 outputs "12.3450000000000"). I don't want it to output the trailing 0s.

you can format the number in scientific notation but to control which numbers are formatted I think you must write some sort of if else

How can I get Numbers 3.2 to recognise 1e-5 as scientific notation?

I just changed from Numbers '09 (2.3) to Number 3.2 on Mavericks (OS X 10.9.3) and the new version doesn't seem to recognise "e" or "E" as scientific notation. When I set the cell format to scientific and type "0.0015", Numbers returns "1.5×10^-03". I would however prefer to obtain "1.5e-3". And vice versa: if, after setting the cell format to scientific, I type "1.5e-3", it automatically formats the cell as text and I can't get it to recognise it as scientific notation. With "E" instead of "e", the problem is exactly the same. Does anyone know how I can change this setting? I already tried to search for an answer to my question, but couldn't find anything...

if, after setting the cell format to scientific, I type "1.5e-3", it automatically formats the cell as text and I can't get it to recognise it as scientific notation.
I can't duplicate the problem here, either when the cells are formatted as Automatic or as Scientific:
When you type 1.5e-3 are you making sure not to enter a space after the e? (When I type a space the cell automatically formats as Text.)

How let labview to verify string is in Scientific Notation.

Hey all,
I want labview to convert a spreadsheet string to an array. This is easy using the 'spreadsheet string to array' tool. The only problem I've got is that I get the string from a RS232 device and it is time critical.
Example:
If I read the data from the buffer it gives me:
+1.50337800E+00,+1.70316300E+00 for two channels, this is converted and accepted
if there is a small delay I get:
+1.50337800E+00,+1.70316
This will also be accepted because +1.70316 is also recognized as a number.
How can program labview to check that every number it reads is according to the Scientific Notation?
Thanks
Solved!

MANY times there are artificial constraints (like the time allocated to fix the problem) so you just have to make a band-aid like this. I get grumpy when I'm forced to program a workaround instead of a fix.

Converting scientific notation string to number?

This is raising an error:

How do you convert scientific notation strings to numbers?
This is coming from XML. I can probably have the XML written so that it's not scientific notation.
Tim

Here's a not-so-pretty way:
Local StringVar Array x;
Local StringVar mantissa;
Local StringVar exponent := "0";
// Split into mantissa and exponent parts.
x:= Split("24.2233E+2", "e", 2, 1);
mantissa := x[1];
If (UBound(x) = 2)
Then
    exponent := x[2];
// CDbl cannot interpret leading positive sign, so removie
If Left(mantissa, 1) = "+"
Then
    mantissa := Right(mantissa, Length(mantissa) - 1);
If Left(exponent, 1) = "+"
Then
    exponent := Right(exponent, Length(exponent) - 1);
// Compute number
CDbl(mantissa) * 10 ^ CDbl(exponent);

How to prevent display in scientific notation

Why Number displayed in scientific notation

I have tried to add two numbers and got a result displayed in scientific notation.
Then I have used the 'decimalformat()' function and result is wrong.
How can display the correct result. Please help
Please see the code I have used
<cfset N1=1>
<cfset N2=9999999999999899999999>
<cfset RESULT = N1+ N2>
<cfoutput>

</cfoutput>
result :

92,233,720,368,547,760.00
Thanks in advance

I think in floating point math adding 1 to 9999999999999899999999 is going to be a meaningless operation as by the time one converts 1 to a floating point of the scale & precision needed to represent 9999999999999899999999, it's going to lose any significance (ie: it's going to basically be represented as zero).
You'll need to do a search on how to deal with numbers of very high precision & scale. I don't have any code to hand. Have you done any of your own investigation on how to deal with this?
