问题 I am writing a program to add two large numbers in C . My integer array result holds the sum of the two numbers (which were also stored in arrays). For example, if the result array is [0,0,3,2] (actual array size is 20) If 32 is my actual result, how can I display the contents of the result array without the leading zeros ? #include <stdio.h> #include <string.h> #include <stdlib.h> #define BASE 10 void align(int A[],int n); void add(int A[],int B[], int C[]); void Invert(int* a, int n); int

Javascript variable with leading zeroes

问题 Javascript behaves differently with values having leading zeroes. alert(b) - prints different value. var a = 67116; var b = 00015; alert(a); alert(b); I am more interested to know What conversion is applied here by javascript inside alert(b) ? (If i have them in double quotes. They work fine.) 回答1: Since js is weakly typed it thinks var b = 00015 is an octal number see this question for solution 回答2: A leading 0 makes the value an octal literal, so the value you put will be interpreted as a

SQLite function to format numbers with leading zeroes?

由 穿精又带淫゛_ 提交于 2019-12-03 10:47:56
问题 I’ve got an SQLite database that will need to contain products. Those products have a fixed-format composite product number, consisting of category, group and product number (cccccc.gg.ppp). Every time a new product is inserted, the new product number should be built using the category and group numbers, followed by the highest product number in that group incremented with one. To that end, I was thinking of storing all three numbers in separate fields, and use a view to dynamically assemble

Create leading zero in Oracle

由 China☆狼群 提交于 2019-12-01 22:45:54
I am using Adempiere which has database Oracle I have window called Stock Code from table called M_StockCode The fields are Code and Description . Currently, Code data type is Number and Description is Varchar2 I want to input Sparepart with Code 01 , and Body Repair with Code 02 . As I input the data in Adempiere and save it, what will show is Sparepart with Code 1 (without leading zero) I've tried putting LPAD function but it's still failed. How can I put 01 both in Adempiere interface and in database? Any suggestion will be appreciated :) A NUMBER cannot have leading zero, a STRING can. If

How to display the leading zero's in a number of oracle

由 送分小仙女□ 提交于 2019-12-01 05:40:42
I have an oracle column(artnr) contains a length of 1 which is of type number(9). I want to update the number as following... Example : If number is 0 then it should be 00000 If number is 1 then it should be 00001 If number is 12 the it should be 00012 Remember : here 00000,0000, and 00012 are of number datatypes The following are the methods I have tried but failed.. UPDATE pitb.toestel b SET b.artnr = LPAD (b.artnr, 5, 0) WHERE b.idinventaris = 403743; Failed because Lpad can only be applied on strings UPDATE pitb.toestel b SET b.artnr = TO_NUMBER (TO_CHAR (artnr, '00009'), '00009') WHERE b

How to count leading zeros in a 32 bit unsigned integer [closed]

Could anyone tell me please what is an efficient algorithm to count the number of leading zeroes in a 32-bit unsigned integer in C programming? This discussion assumes that your compiler either doesn't support the operation or that it doesn't produce good enough assembly. Note that both of these are unlikely nowadays so I'd recommend just using __builtin_clz for gcc or equivalent on your compiler. Note that determining which is the "best" clz algo can only be done by you. Modern processors are complicated beasts and the performance of these algorithm will heavily depend on the platform you run

Get rid of leading zeros for date strings in Python? [duplicate]

This question already has an answer here: Python strftime - date without leading 0? 17 answers Is there a nimble way to get rid of leading zeros for date strings in Python? In the example below I'd like to get 12/1/2009 in return instead of 12/01/2009. I guess I could use regular expressions. But to me that seems like overkill. Is there a better solution? >>> time.strftime('%m/%d/%Y',time.strptime('12/1/2009', '%m/%d/%Y')) '12/01/2009' See also Python strftime - date without leading 0? @OP, it doesn't take much to do a bit of string manipulation. >>> t=time.strftime('%m/%d/%Y',time.strptime(

Why does Python 3 allow “00” as a literal for 0 but not allow “01” as a literal for 1?

Why does Python 3 allow "00" as a literal for 0 but not allow "01" as a literal for 1? Is there a good reason? This inconsistency baffles me. (And we're talking about Python 3, which purposely broke backward compatibility in order to achieve goals like consistency.) For example: >>> from datetime import time >>> time(16, 00) datetime.time(16, 0) >>> time(16, 01) File "<stdin>", line 1 time(16, 01) ^ SyntaxError: invalid token >>> Per https://docs.python.org/3/reference/lexical_analysis.html#integer-literals : Integer literals are described by the following lexical definitions: integer ::=
