This is probably the best way, since it’s reliable and works on old browsers: function indexOfMax(arr) { if (arr.length === 0) { return -1; } var max = arr[0]; var maxIndex = 0; for (var i = 1; i < arr.length; i++) { if (arr[i] > max) { maxIndex = i; max = arr[i]; } … Read more
Since PHP 5.5 you can use array_column to get an array of values for specific key, and max it. max(array_column($array, ‘Total’))
For float have a look at sys.float_info: >>> import sys >>> sys.float_info sys.floatinfo(max=1.7976931348623157e+308, max_exp=1024, max_10_exp=308, min=2.2 250738585072014e-308, min_exp=-1021, min_10_exp=-307, dig=15, mant_dig=53, epsil on=2.2204460492503131e-16, radix=2, rounds=1) Specifically, sys.float_info.max: >>> sys.float_info.max 1.7976931348623157e+308 If that’s not big enough, there’s always positive infinity: >>> infinity = float(“inf”) >>> infinity inf >>> infinity / 10000 inf The long type has … Read more
Assuming df has a unique index, this gives the row with the maximum value: In [34]: df.loc[df[‘Value’].idxmax()] Out[34]: Country US Place Kansas Value 894 Name: 7 Note that idxmax returns index labels. So if the DataFrame has duplicates in the index, the label may not uniquely identify the row, so df.loc may return more than … Read more
You should try it, just have a script that sleeps for more than your maximum execution time. <?php sleep(ini_get(‘max_execution_time’) + 10); ?> Spoiler: Under Linux, sleeping time is ignored, but under Windows, it counts as execution time.
If rownumber() over(…) is available for you …. select OrderNO, PartCode, Quantity from (select OrderNO, PartCode, Quantity, row_number() over(partition by OrderNO order by DateEntered desc) as rn from YourTable) as T where rn = 1
I achieved 1600k concurrent idle socket connections, and at the same time 57k req/s on a Linux desktop (16G RAM, I7 2600 CPU). It’s a single thread http server written in C with epoll. Source code is on github, a blog here. Edit: I did 600k concurrent HTTP connections (client & server) on both the … Read more
From the spec, §15.9.1.1: A Date object contains a Number indicating a particular instant in time to within a millisecond. Such a Number is called a time value. A time value may also be NaN, indicating that the Date object does not represent a specific instant of time. Time is measured in ECMAScript in milliseconds … Read more
If you’re using SQL Server 2008 (or above), then this is the better solution: SELECT o.OrderId, (SELECT MAX(Price) FROM (VALUES (o.NegotiatedPrice),(o.SuggestedPrice)) AS AllPrices(Price)) FROM Order o All credit and votes should go to Sven’s answer to a related question, “SQL MAX of multiple columns?” I say it’s the “best answer” because: It doesn’t require complicating … Read more
An array could theoretically have at most 2,147,483,647 elements, since it uses an int for indexing. The actual limit is slightly lower than this, depending on the type contained within the array. However, there is a 2GB maximum single object restriction in the .NET CLR, even in 64bit. This was done by design. You can … Read more
