Returns average of numeric values in a given column. We have table as shown in figure that will be used to perform different aggregate functions. The table name is Marksheet. Select AVG(MarksObtained) From Marksheet The average function doesn't consider rows with NULL value in the field used ...

There are numerous ways to convert numeric types to strings in Julia: julia> a = 123 123 julia> string(a) "123" julia> println(a) 123 The string() function can also take more arguments: julia> string(a, "b") "123b" You can also insert (aka ...

In Julia, as in many other languages, it is possible to interpolate by inserting values defined by variables into strings. For a simple example: n = 2 julia> MyString = "there are $n ducks" "there are 2 ducks" We can use other types than numeric, e.g. Result = false j...

Animation curves allows you to change a float parameter as the animation plays. For example, if there is an animation of length 60 seconds and you want a float value/parameter, call it X, to vary through the animation (like at animation time = 0.0s; X = 0.0 , at animation time = 30.0s; X = 1.0, at...

In PHP 7.1, the void return type was added. While PHP has no actual void value, it is generally understood across programming languages that a function that returns nothing is returning void. This should not be confused with returning null, as null is a value that can be returned. function lacks_re...

Julia has a built-in implementation of semantic versioning exposed through the VersionNumber type. To construct a VersionNumber as a literal, the @v_str string macro can be used: julia> vers = v"1.2.0" v"1.2.0" Alternatively, one can call the VersionNumber constructor; n...

For example you want to use surfaceView in ng2-nativescript. As we don't have surfaceView in nativescript we should use placeholder. first we should import the requirements: import {Component} from "@angular/core"; import placeholder = require("ui/placeholder"); let applicat...

Define the function using the vararg keyword. fun printNumbers(vararg numbers: Int) { for (number in numbers) { println(number) } } Now you can pass as many parameters (of the correct type) into the function as you want. printNumbers(0, 1) // Prints "0&qu...
