"min" and "max" in "std.algorithm" can be used with single values to pick up the min and max values, but it didn't mention how they can be used with ranges in the documentation:

https://dlang.org/phobos/std_algorithm_comparison.html#.min

The docs do mention minElement and maxElement (the range versions) under the "See Also" heading, but you're right that it's not super clear why they're mentioned.

They said " If at least one of the arguments is NaN, the result is an unspecified value. See std.algorithm.searching.minElement for examples on how to cope with NaNs.", as a beginner how can I guess what "NaNs" means or if it refers to ranges?!

When something unexplained, it might be because it's assumed to be general knowledge. So you can search for that term on a web search engine. The good ones immediately come up with the wikipedia entry for the computing term. Google has a definition and a bunch of ads but, below these, the same wikipedia entry.

That's called "unorderedness": http://ddili.org/ders/d.en/floating_point.html#ix_floating_point.unordered > as a beginner how can I guess what "NaNs" > means or if it refers to ranges?! You can use the index: ;) http://ddili.org/ders/d.en/ix.html There are a couple of entries for 'nan' there. Ali
