问题 I'm trying to write a function to present thousands and millions into K's and M's For instance: 1000 = 1k 1100 = 1.1k 15000 = 15k 115000 = 115k 1000000 = 1m Here is where I got so far: func formatPoints(num: Int) -> String { let newNum = String(num / 1000) var newNumString = "\(num)" if num > 1000 && num < 1000000 { newNumString = "\(newNum)k" } else if num > 1000000 { newNumString = "\(newNum)m" } return newNumString } formatPoints(51100) // THIS RETURNS 51K instead of 51.1K How do I get

问题 What is the simplest and most-pythonic way to parse a DICOM file? A native Python implementation without the use of non-Python libraries would be much preferred. DICOM is the standard file format in digital medical imaging (look here for more information). There are some C/C++ libraries that support reading (a subset) of DICOM files. Two or three of them even have Python bindings. A native Python parser would serve two purposes for me: No need to build any external C/C++ libraries. Learn

问题 How do I prevent String.format("%.2f", doubleValue); from rounding off (round half up algorithm) instead of just truncating it? e.g. doubleValue = 123.459 after formatting, doubleValue = 123.46 I just want to discard the last digit, 123.45 I know there are other ways to do this, I just want to know if this is possible using the String.format. 回答1: You can always set the rounding mode: http://java.sun.com/javase/6/docs/api/java/math/RoundingMode.html and then use String.Format() HALF_EVEN is

问题 I had tried to find some work done but I haven't had luck. Any ideas? Examples: Week, 1, 2001 => 2001-01-01 Week, 26, 2007 => 2007-06-01 回答1: As Kevin's code does not implement ISO 8601 properly (first day of the first week of year must be a Monday), I've corrected it and ended up with (also check it on jsfiddle): function firstDayOfWeek(week, year) { if (year==null) { year = (new Date()).getFullYear(); } var date = firstWeekOfYear(year), weekTime = weeksToMilliseconds(week), targetTime =

问题 I'd like to know if there is a formatting letter for PHP's date() that allows me to print minutes without leading zeros, or whether I have to manually test for and remove leading zeros? 回答1: Use: $minutes = intval(date('i')); 回答2: For times with more information than just minutes: ltrim() - Strip whitespace (or other characters) from the beginning of a string ltrim(date('i:s'), 0); returns: 8:24 回答3: According to the PHP Documentation, the date() function does not have a placeholder for
