number-formatting

I have a large vector of strings of the form: Input = c("1,223", "12,232", "23,0") etc. That's to say, decimals separated by commas, instead of periods. I want to convert this vector into a numeric vector. Unfortunately, as.numeric(Input) just outputs NA . My first instinct would be to go to strsplit , but it seems to me that this will likely be very slow. Does anyone have any idea of a faster option? There's an existing question that suggests read.csv2 , but the strings in question are not directly read in that way. as.numeric(sub(",", ".", Input, fixed = TRUE)) should work. scan(text=Input,

I am using NumberFormat.getCurrencyInstance(myLocale) to get a custom currency format for a locale given by me. However, this always includes the currency symbol which I don't want, I just want the proper currency number format for my given locale without the currency symbol. Doing a format.setCurrencySymbol(null) throws an exception.. The following works. It's a bit ugly, but it fulfils the contract: NumberFormat nf = NumberFormat.getCurrencyInstance(); DecimalFormatSymbols decimalFormatSymbols = ((DecimalFormat) nf).getDecimalFormatSymbols(); decimalFormatSymbols.setCurrencySymbol(""); (

I have this string : 000000000000100 and need to convert it to: 1,00 So, the rules are: Divide the number by 100 and use a comma as decimal separator Strip leading zeros Keep two decimals From the PHP Manual page on number_format : string number_format ( float $number , int $decimals = 0 , string $dec_point = '.' , string $thousands_sep = ',' ) If you want numbers like 123456 be formatted as 1234,45 , use: echo number_format($number / 100, 2, ",", ""); If you need a dot as thousands separator ( 1.234,56 ): echo number_format($number / 100, 2, ",", "."); The zeros are automatically removed by
