OLD: A quick and dirty solution can be to use a function like this: function toChars($number) { $res = base_convert($number, 10,26); $res = strtr($res,’0123456789′,’qrstuvxwyz’); return $res; } The base convert translate your number to a base where the digits are 0-9a-p then you get rid of the remaining digits with a quick char substitution. As … Read more
We could use parse_number from readr package which removes any non-numeric characters. library(readr) parse_number(df$COL1) #[1] 54345 65231 76234
This code shows the example how to prevent entering non digit symbols. angular.module(‘app’). directive(‘onlyDigits’, function () { return { restrict: ‘A’, require: ‘?ngModel’, link: function (scope, element, attrs, modelCtrl) { modelCtrl.$parsers.push(function (inputValue) { if (inputValue == undefined) return ”; var transformedInput = inputValue.replace(/[^0-9]/g, ”); if (transformedInput !== inputValue) { modelCtrl.$setViewValue(transformedInput); modelCtrl.$render(); } return transformedInput; }); … Read more
Perhaps you’re looking for BigRational? Microsoft released it under their BCL project on CodePlex. Not actually sure how or if it will fit your needs. It keeps it as a rational number. You can get the a string with the decimal value either by casting or some multiplication. var r = new BigRational(5000, 3768); Console.WriteLine((decimal)r); … Read more
Try this: System.Globalization.CultureInfo customCulture = (System.Globalization.CultureInfo)System.Threading.Thread.CurrentThread.CurrentCulture.Clone(); customCulture.NumberFormat.NumberDecimalSeparator = “.”; System.Threading.Thread.CurrentThread.CurrentCulture = customCulture;
There’s the intToBits function that converts any integer to a vector of 32 raws, so you can do this: decimals <- c(3,5,11,4) m <- sapply(decimals,function(x){ as.integer(intToBits(x))}) m > m [,1] [,2] [,3] [,4] [1,] 1 1 1 0 [2,] 1 0 1 0 [3,] 0 1 0 1 [4,] 0 0 1 0 [5,] 0 … Read more
In this case you want to constrain your generic to the IComparable interface, which gives you access to the CompareTo method, since this interface allows you to answer the question ShouldBeGreaterThan. Numeric types will implement that interface and the fact that it also works on strings shouldn’t bother you that much.
a.sort(function(a,b){return a – b}) These can be confusing…. check this link out.
No, this is not possible. The key will always be converted to a string. See Property Accessor docs Property names must be strings. This means that non-string objects cannot be used as keys in the object. Any non-string object, including a number, is typecasted into a string via the toString method. > var foo = … Read more
Update for C++11 As of the C++11 standard, string-to-number conversion and vice-versa are built in into the standard library. All the following functions are present in <string> (as per paragraph 21.5). string to numeric float stof(const string& str, size_t *idx = 0); double stod(const string& str, size_t *idx = 0); long double stold(const string& str, … Read more
