made input into string but it's not showing all the numbers I need

I have to extract certain numbers from an input. I turned it into a string to use the extractAfter and extractBefore functions. This is what the code looks like:

inputID = input('Please input an ID:');
createDate = input('Please input the creation date in MMDDYYYY format:');
str1 = string(inputID)
%str1 is equal to the numbers of the inputted ID
str2 = extractAfter(str1,5)
%str2 is the ID after the first 5 numbers have been removed
str3 = extractBefore(str2,9)
%str3 is the str2 after the last 10 numbers have been removed
%str3 results in the part of ID that is the supposed creation date

While the extracting is working as it should, the string function turns my input into "1.08592017101e+18." When I extract the parts, it doesn't include the other numbers after the "e," which I need. Is there a way to make it into a string without it becoming "1.08592017101e+18" ?

sorry, the comment after str3 should say last 9 numbers, not 10

There can be multiple ways to resolve this. One simple way is to using sprintf() to specify the format. The code will be like below:

inputID = input('Please input an ID:');
createDate = input('Please input the creation date in MMDDYYYY format:');
str1 = sprintf('%18d',inputID);
%str1 is equal to the numbers of the inputted ID
str2 = extractAfter(str1,5)
%str2 is the ID after the first 5 numbers have been removed
str3 = extractBefore(str2,9)
%str3 is the str2 after the last 9 numbers have been removed
%str3 results in the part of ID that is the supposed creation date

I hope this is what you wanted.
