leading-zero

问题 How do we we add a zero in front of the decimal place in PHP? I want to convert .96 to 0.96 Now in my php code, I'm fetching data by using wordpress get_attribute <td><?php echo $_product->get_attribute('pa_carat');?></td> 回答1: The function you want is number_format echo number_format(0.96, 2); Alternatively you can just check for and prepend it if it is missing. if ($num[0] == '.') $num = '0' . $num; This wont handle negative numbers though, you would need to write a little more logic for

问题 I'm trying to import data into a table. I'm doing a bulk insert. I've created the table using a CREATE statement where all fields are nvarchar(max). I cannot understand why when the import is done, the data with leading zeros has been changed to scientific notation. Why does it not stay as text and preserve the leading zeros? 回答1: I suggest that you define the number of zeros that do you want and then make an update. Here is an example with 10 zeros. create table #leadingZeros(uglynumber

问题 I have a column as below. 9453, 55489, 4588, 18893, 4457, 2339, 45489HQ, 7833HQ I would like to add leading zero if the number is less than 5 digits. However, some numbers have "HQ" in the end, some don't.(I did check other posts, they dont have similar problem in the "HQ" part) so the finally desired output should be: 09453, 55489, 04588, 18893, 04457, 02339, 45489HQ, 07833HQ any idea how to do this? Thank you so much for reading my post! 回答1: A one-liner using regular expressions: my

问题 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

问题 I have several alphanumeric strings like these listOfNum = ['000231512-n','1209123100000-n00000','alphanumeric0000', '000alphanumeric'] The desired output for removing trailing zeros would be: listOfNum = ['000231512-n','1209123100000-n','alphanumeric', '000alphanumeric'] The desired output for leading trailing zeros would be: listOfNum = ['231512-n','1209123100000-n00000','alphanumeric0000', 'alphanumeric'] The desire output for removing both leading and trailing zeros would be: listOfNum =

问题 I believe that I've encountered a bug in how Laravel 5.3 handles eager loading when the foreign key is a string which contains zerofilled numbers. I have two models (using a mysql backend), School and Student . The id field in School is a string, and contains 5-digit numbers assigned by the state, which include leading zeros. Student BelongsTo School , and contains a school_id field which is defined identically to the id field in School . I have done some testing, and I'm finding that when I

问题 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 >>> 回答1: Per https://docs.python.org/3/reference/lexical_analysis

问题 This question already has answers here : strip leading zeros in awk program (5 answers) Closed 5 years ago . I am generating a report using an awk file to pull data and write to another file. Filename: dosreport.awk. This code prints a material number like this 000000000000787301 if (substr($0, 1, 7) == "E2EDP19" && E2EDP19seen == 1) { printf " " substr($2, 6); E2EDP19seen=E2EDP19seen +1; } The relevant data is E2EDP19001 02002000000000000797578 I need the leading zeros stripped to just give

问题 I'm using Excels find and replace to remove hyphens from long numbers. They are mixed between birth dates and organisation numbers that have been filled with leading zeros to have the same number of characters. There are a LOT of numbers so find and replace seems to be the simplest solution to remove the hyphens. But when i use find and replace the leading zeros are truncated and I have not found a solution to keep them afterwards. For example i have: 19551230-1234 01234567-8901 and after
