sub function definition, sub function meaning | English dictionary. function. 4 (Also called) map, mapping (Maths, logic) a relation between two sets that associates a unique element (the value) of the second (the range) with each element (the argument) of the first (the domain): a many-one relation.
In mathematics, a function is defined as a relationship between defined values and one or more variables. For example, a simple math function may be: y = 2x. In this example, the relationship of y to x is that y is twice as much as the value assigned to x. While math functions can be far more complex than this, most are simple relative to functions used in computer programming. This may be why math functions are often referred to as expressions, while computer functions are often called procedures or subroutines. Computer functions are similar to math functions in that they may reference parameters, which are passed, or input into the function. If the example above were written as a computer function, x would be the input parameter and y would be the resulting output value. It might look something like this: function double(x) { $y = 2 * x; return $y;}
