I'm using Spring localization with a properties file and basically want to localize {0}€ with the parameter being a BigDecimal. The localzied output will show 1€ instead of 1.00€ while 1.01€ will be displayed as should be.
Is there a way to leave blank decimal places untouched?
You can define message format for numbers this way
product.price = Price: {0, number, #.##}€

I want to apply data validation to my column so as to only accept whole numbers.
However I want these to be displayed with a dot so as to make it easier to read later on.
e.g. input = 14354 which is valid and then displayed 14.354
the data validation regular expression I am ussing is:
=regexmatch(to_text(A2);"^\d+\.*\d+$")
and the custom formatting is:
#,##
for most this working fine, large numbers are displayed with the '.' and things it shouldnt accept it is rejecting.
However, in the case of numbers which are entered with a decimal point as these are hidden, it is accepting it as valid.
It is also changing the format to auto atic and reading as date such entries like: 15.4
I should point out that I am using sheets in spanish and therefore the , is the marker for decimal places.
What am i missing here??
Select the cell range then go to Data > Data validation...
Add a custom formula rule:
=mod(A1;1)=0
Try this one:
=and(regexmatch(to_text(A2);"^\d+(\.\d{3})*$");mod(A2;1)=0)
Improved your formula to only accept a dot when it is followed by 3 numbers (this way, we invalidate the date e.g A2)
Combining the improved formula of yours and Aresvik's modulo answer, we need to check if the value does not have decimal. (this way, we invalidate the decimal e.g A6)
When both returns true, this shall confirm that the number inputted is a whole number with no decimal and not a date.
Output:
Invalid inputted values:
A2 - 15.4
A6 - 16412,212
We are using java.text.NumberFormat class to format the currency values using the method getInstance(Locale paramLocale). Our issue is when we pass es_CO(Columbia) language code it automatically formats it in value 123,00 instead of 123.00. Is there a way to format with dot instead of comma?
I am using Spring platform(hybris)
Please note due to business reasons it is not possible for me to change the locale.
You can use DecimalFormat to have your own format.
Look at this How can I format a String number to have commas and round?
I have some HTML page and on this page I will provide the possibility for free text.
For example, it is possible to write in textbox either: 10 or 10 apples.
In a case of writing 10 apples I got NumberFormatException which is correct, but for me will be good to extract only number automatically without javascript writing.
Is it possible to map string from HTML page to the number in my java entity? May be with some annotation or somehow else?
Try:
final String stripped = textbox.getText().replaceAll("[^0-9]", "");
This takes the contents of the text field and strips out any characters that aren't digits. If you need to deal with floating point or negative numbers, it can be done, but becomes more complicated.
I need to format values in the UI in different ways:
No decimals: 15
One decimal: 15.4
Two decimals: 15.44
Percentage no decimals: 15%
Percentage one decimal: 15.4%
Percentage two decimals: 15:44%
What is the recommended way to achieve this? To use Thymeleaf numbers formatter to format to integer or decimal (and add % sign myself if needed). Or should I configure one or more Spring formatters with different formatting patterns?
If you only show the value at one page I would format it in the template. If it's a form field or you need it on different pages I would use the converter/formatter-approach of spring.
I am doing some localization testing and I have to test for strings in both English and Japaneses. The English string might be 'Waiting time is {0} minutes.' while the Japanese string might be '待ち時間は{0}分です。' where {0} is a number that can change over the course of a test. Both of these strings are coming from there respective property files. How would I be able to check for the presence of the string as well as the number that can change depending on the test that's running.
I should have added the fact that I'm checking these strings on a web page which will display in the relevant language depending on the location of where they are been viewed. And I'm using watir to verify the text.
You can read elsewhere about various theories of the best way to do testing for proper language conversion.
One typical approach is to replace all hard-coded text matches in your code with constants, and then have a file that sets the constants which can be updated based on the language in use. (I've seen that done by wrapping the require of that file in a case statement based on the language being tested. Another approach is an array or hash for each value, enumerated by a variable with a name like 'language', which lets the tests change the language on the fly. So validations would look something like this
b.div(:id => "wait-time-message).text.should == WAIT_TIME_MESSAGE[language]
To match text where part is expected to change but fall within a predictable pattern, use a regular expression. I'd recommend a little reading about regular expressions in ruby, especially using unicode regular expressions in ruby, as well as some experimenting with a tool like Rubular to test regexes
In the case above a regex such as:
/Waiting time is \d+ minutes./ or /待ち時間は\d+分です。/
would match the messages above and expect one or more digits in the middle (note that it would fail if no digits appear, if you want zero or more digits, then you would need a * in place of the +
Don't check for the literal string. Check for some kind of intermediate form that can be used to render the final string.
Sometimes this is done by specifying a message and any placeholder data, like:
[ :waiting_time_in_minutes, 10 ]
Where that would render out as the appropriate localized text.
An alternative is to treat one of the languages as a template, something that's more limited in flexibility but works most of the time. In that case you could use the English version as the string that's returned and use a helper to render it to the final page.
