14 Money input format:
1. There are four kinds of representation of the money we can accept: "10000.00" and "10000.00," and not "points" of the "10000" and "10000" : ^ 1-9] [[0-9] * $2. This means that any one does not begin with 0, but it also means that a character "0" is not through, so we use the form below: ^ (0 | [1-9] [0-9] *) $3. A 0 or a number that doesn't start with 0. We can also allow the beginning there is a minus sign: ^ (0 | -? [1-9][0-9]*)$4. This represents a 0 or a potentially negative number that does not begin with a 0. Let the user start with 0. Let's get rid of the minus, because money can't be negative. ^[0-9]+(.[0-9]+)? $5. Must be behind the decimal point should be at least 1 digit, so it is not through "10.", but "10" and "10.2" is through: ^ [0-9] + (. [0-9] {2})? $6. So we must have two decimal point behind, if you think that is too harsh, it can be: ^ [0-9] + (. [0-9] {1, 2})? $7. This allows the user to write only one decimal digit. Below we should consider a comma in the digital, we can be like this: ^ [0-9] {1, 3} ([0-9] {3}), * (. [0-9] {1, 2})? The $8.1 to 3 number, followed by any comma + 3 Numbers, comma become optional, rather than having to: ^ ([0-9] + | [0-9] {1, 3} ([0-9] {3}), *) (. [0-9] {1, 2})? $Note: This is the final result, remember that "+" can be replaced with "*" if you think empty strings are acceptable (strange, why?). And finally, don't forget to get rid of that backslash when you're using a function, that's where the usual mistakes areCopy the code15 XML file: ^([a-za-z]+-?) +[a-zA-Z0-9]+\.[x|X][m|M][l|L]$
