You are doing this fine. The problem is with the inaccuracy of floating point numbers. Why are floating point numbers so inaccurate? If you wish to display this number then use: heights[i].toFixed(2); Note that toFixed() returns a string and you will have to convert back to a float (parseFloat()) if you want to perform more … Read more
The iteration order of unordered associative containers can only change when rehashing as a result of a mutating operation (as described in C++11 23.2.5/8). You are not modifying the container between iterations, so the order will not change. Although the specification doesn’t explicitly state that rehashing can’t occur at any other time, doing so would … Read more
Of course that set x=%%g and a substring extraction of x should work, but be aware that if the substring is taken inside a FOR loop, it must be done with ! instead of % (Delayed Expansion): setlocal EnableDelayedExpansion for /d %%g in (%windir%\Assembly\gac_msil\*policy*A.D*) do ( set x=%%g echo !x:~29! )
–> is not a new operator. It is just a conjunction of the operators — and >. You first compare, and then decrement the variable. That is, i –> 0 becomes effectively i > 0; //Compare i–; //and decrement
Unfortunately, this is not easy to read. You are misreading the second case of the for statement. The first semicolon is an integral part of declaration and thus hidden to your eyes. You can easily check such syntax questions by looking into Annex A. There you have: (6.7) declaration: declaration-specifiers init-declarator-listopt ; static_assert-declaration
It is equivalent to while(true). A for-loop has three elements: initializer condition (or termination expression) increment expression for(;;) is not setting any of them, making it an endless loop. Reference: The for statement
for (i in 1..4 step 2) print(i) // prints “13” See here: http://kotlinlang.org/docs/reference/ranges.html
You concrete problem is caused because you’re mixing discouraged and old school scriptlets <% %> with its successor EL ${}. They do not share the same variable scope. The allFestivals is not available in scriptlet scope and the i is not available in EL scope. You should install JSTL (<– click the link for instructions) … Read more
