Removing Digits from a Number

一笑奈何 提交于 2019-12-01 03:24:26
问题 Does anybody know if there is a way of removing (trimming) the last two digits or first two digits from a number. I have the number 4131 and I want to separate that into 41 and 31, but after searching the Internet, I've only managed to find how to remove characters from a string, not a number. I tried converting my number to a string, then removing characters, and then converting it back to a number, but I keep receiving errors. I believe I will be able to receive the first two digit by

PHP - Remove last character of file

倾然丶 夕夏残阳落幕 提交于 2019-12-01 03:22:18
I have a little php script that removes the last character of a file. $contents = file_get_contents($path); rtrim($contents); $contents = substr($contents, 0, -1); $fh = fopen($path, 'w') or die("can't open file"); fwrite($fh, $contents); fclose($fh); So it reads in the file contents, strips off the last character and then truncates the file and writes the string back to it. This all works fine. My worry is that this file could contain a lot of data and the file_get_contents() call would then hold all this data in memory which could potentially max out my servers memory. Is there a more

Function to trim leading and trailing whitespace in vba

China☆狼群 提交于 2019-12-01 02:58:34
问题 I have checked quite a few suggestions re trimming leading & trailing whitespace in vba (excel, incidentally). I have found this solution, but it also trims å ä ö (also caps) and I am too weak in regex to see why: Function MultilineTrim (Byval TextData) Dim textRegExp Set textRegExp = new regexp textRegExp.Pattern = "\s{0,}(\S{1}[\s,\S]*\S{1})\s{0,}" textRegExp.Global = False textRegExp.IgnoreCase = True textRegExp.Multiline = True If textRegExp.Test (TextData) Then MultilineTrim = textRegExp

MySQL truncate text with ellipsis

倖福魔咒の 提交于 2019-12-01 02:45:41
Suppose I have a MySQL table of one column: "Message". It is of type TEXT. I now want to query all rows, but the text can be large (not extremely large but large) and I only want to get a summary of them. For example the result can be populated into a list. Is there a way to trim the text to a specific length (say, 10 characters), and add ellipsis if the text is trimmed? For example: Message ----------- 12345678901234 1234567890 12345 12345678901 Query result: 1234567... 1234567890 12345 1234567... Thanks! select case when length(message) > 7 then concat(substring(message, 1, 7), '...') else

In Haskell, how do you trim whitespace from the beginning and end of a string?

How do you trim whitespace from the start and end of a string? trim " abc " => "abc" Edit: Ok, let me be a little clearer. I did not understand that string literals were treated so differently from Strings. I would like to do this: import qualified Data.Text as T let s :: String = " abc " in T.strip s Is this possible in Haskell? I am using -XOverloadedStrings but that appears only to work for literals. If you have serious text processing needs then use the text package from hackage: > :set -XOverloadedStrings > import Data.Text > strip " abc " "abc" If you're too stubborn to use text and don

Allocatable character variables in Fortran

北城以北 提交于 2019-11-30 23:10:46
问题 My code (stripped down to what I think is relevant for this question) is PROGRAM test IMPLICIT NONE CHARACTER(len=37) input CHARACTER(len=:), allocatable :: input_trim WRITE(*,*) 'Filename?' READ(*,*) input ALLOCATE(character(len=LEN(TRIM(input))) :: input_trim) input_trim=trim(input) . . . END PROGRAM test It works fine with Intel's Fortran compiler, however gfortran gives me a couple of errors, the first one being in the line saying CHARACTER(len=:), allocatable :: input_trim I'm not sure

How to trim spaces of model in ASP.NET MVC Web API

99封情书 提交于 2019-11-30 20:07:06
What is the best way to trim all the properties of the model passed to the MVC web api (post method with complex object). One thing simply can be done is calling Trim function in the getter of all the properties. But, I really do not like that. I want the simple way something like the one mentioned for the MVC here ASP.NET MVC: Best way to trim strings after data entry. Should I create a custom model binder? To trim all incoming string values in Web API, you can define a Newtonsoft.Json.JsonConverter : class TrimmingConverter : JsonConverter { public override bool CanConvert(Type objectType) {

Laravel 5 Validation Trim

问题 I am a beginner in Laravel 5. How can I remove whitespaces in validator?? i have read the documentation but there is no validator for trim(remove whitespaces). here my rules $rules = [ 'name' =>'required', 'email' => 'required|email', 'address' => 'required', 'phones' => 'required' ]; thanks for your answer. 回答1: It's not job for validator to change any input data. Trim validator exists in CodeIgniter, but as to me this isn't right place to perform trim. You can automatically trim all input
