The rules are as follows: st is used with numbers ending in 1 (e.g. 1st, pronounced first) nd is used with numbers ending in 2 (e.g. 92nd, pronounced ninety-second) rd is used with numbers ending in 3 (e.g. 33rd, pronounced thirty-third) As an exception to the above rules, all the “teen” numbers ending with 11, … Read more
I had a similar instance where I wanted to use .toFixed() where necessary, but I didn’t want the padding when it wasn’t. So I ended up using parseFloat in conjunction with toFixed. toFixed without padding parseFloat(n.toFixed(4)); Another option that does almost the same thing This answer may help your decision Number(n.toFixed(4)); toFixed will round/pad the … Read more
The simplest way would be to generate two random numbers from 0-50 and add them together. This gives a distribution biased towards 50, in the same way rolling two dice biases towards 7. In fact, by using a larger number of “dice” (as @Falco suggests), you can make a closer approximation to a bell-curve: function … Read more
There are a lot of options: int x = 30; if (Enumerable.Range(1,100).Contains(x)) //true And indeed basic if more elegantly can be written with reversing order in the first check: if (1 <= x && x <= 100) //true Also, check out this SO post for regex options. Notes: LINQ solution is strictly for style points … Read more
You can clear the input field by using $(‘#shares’).val(”);
You can use sprintf: http://php.net/manual/en/function.sprintf.php <?php $num = 4; $num_padded = sprintf(“%02d”, $num); echo $num_padded; // returns 04 ?> It will only add the zero if it’s less than the required number of characters. Edit: As pointed out by @FelipeAls: When working with numbers, you should use %d (rather than %s), especially when there is … Read more
The answer is: re.sub(r'(foo)’, r’\g<1>123′, ‘foobar’) Relevant excerpt from the docs: In addition to character escapes and backreferences as described above, \g will use the substring matched by the group named name, as defined by the (?P…) syntax. \g uses the corresponding group number; \g<2> is therefore equivalent to \2, but isn’t ambiguous in a … Read more
Test if your variable is an instance of numbers.Number: >>> import numbers >>> import decimal >>> [isinstance(x, numbers.Number) for x in (0, 0.0, 0j, decimal.Decimal(0))] [True, True, True, True] This uses ABCs and will work for all built-in number-like classes, and also for all third-party classes if they are worth their salt (registered as subclasses … Read more
A more generalized version: function nFormatter(num, digits) { const lookup = [ { value: 1, symbol: “” }, { value: 1e3, symbol: “k” }, { value: 1e6, symbol: “M” }, { value: 1e9, symbol: “G” }, { value: 1e12, symbol: “T” }, { value: 1e15, symbol: “P” }, { value: 1e18, symbol: “E” } ]; … Read more
Because that’s exactly how the spec says it should work. The number input can accept floating-point numbers, including negative symbols and the e or E character (where the exponent is the number after the e or E): A floating-point number consists of the following parts, in exactly the following order: Optionally, the first character may … Read more
