number-formatting

I have read that money_format is not available on windows, and on some Linux distributions (i.e. BSD 4.11 variants). But I want to write cross-platform library using normal function, when available and using this workaround when not, so my library will be able to run on every PHP-based web server. Is there any simple solution to check whether built-in function is available and if not to include the solution from above? The function money_format() is only defined if the system has strfmon capabilities. For example, Windows does not, so money_format() is undefined in Windows. So you can use this

I'm writing an alarm web app. I have two number inputs, one for the hours, one for the minutes. Thus, when I use my keyboard arrows, they go from 0 to 23/59. Is there an HTML native way to make them go from 00 (01,02, et.) to 23/59 instead ? I'm only worried about the UI aspects as my JS manages the missing 0 anyway. EDIT - As requested : What I have : What I want : Instead of going from 0,1,2 to 59, I'd like to automatically have a leading 0 when the number is smaller than 10 (00,01,02 to 59). I'm afraid there is not native HTML way to do that unless using a Select tag. If you are using a

My objective is to create a customer calculator application for iPhone and I am using Xcode to write my application. My problem, that I cannot find a solution for, is how to format a number that uses decimals (with extra zeros) without switching into scientific notation I tried... buttonScreen.text = [NSString stringWithFormat:@"%0.f",currentNumber]; %0.f formatting always rounds so if the user types in "4.23" it displays "4" %f formats numbers with 6 decimals (typing in '5' displays as '5.000000'), but I don't want to show extra zeros on the end of the number. %10.4f is something else that I

Suppose my data looks like this: df1 = data.frame(A=c(1000000.51,5000.33), B=c(0.565,0.794)) I want to use DataTables and have column A be (1,000,001 ; 5,000) library(DT) datatable(df1) %>% formatPercentage('B', 2) %>% formatRound('A',digits = 0) I know i can use scales library(scales) comma_format()(1000000) but I'm not sure how to combine that with DataTables Thanks! Had this same issue: Try This: require(DT) require(dplyr) df1 = data.frame(A=c(1000000.51,5000.33, 2500, 251), B=c(0.565,0.794, .685, .456)) df1 <- df1 %>% mutate(A=round(A,digits=0)) datatable(df1) %>% formatPercentage('B', 2)

I have a JFormattedTextField which I want to accept numbers in the 5 digit range. The following code works correctly: myNumberBox = new JFormattedTextField(NumberFormat.getIntegerInstance()); However, when I type "12345" into the field and switch focus, a comma is inserted due to my locale, making the text "12,345". How can I prevent commas from being added to my input? Better yet, can they be stripped out even if the user does insert commas? You have to disable the grouping in your NumberFormat object like this: NumberFormat format = NumberFormat.getIntegerInstance(); format.setGroupingUsed
