For example, in the expression (f(x)-1)/(f(x)+1), the function f cannot be called only once with its value used two times since the two calls may return different results. Moreover, in the few languages which define the order of evaluation of the division operator's operands, the value of x must be fetched again before the second call, since ...
The PDF.js contributor community also notes that the browser behavior of PDF.js varies with browser support for PDF.js's required features. [28] Performance and reliability will be the best on Chrome and Firefox, which are fully supported and subject to automated testing.
Example of RecipeML, a simple markup language based on XML for creating recipes. The markup can be converted programmatically for display into, for example, HTML , PDF or Rich Text Format . A markup language is a text-encoding system which specifies the structure and formatting of a document and potentially the relationships among its parts. [ 1 ]
For example, to highlight the text in a heading when the user moves the mouse pointer over it, you can use the style object to enlarge the font and change its color, as shown in the following simple example.
The Math object contains various math-related constants (for example, π) and functions (for example, cosine). (Note that the Math object has no constructor, unlike Array or Date. All its methods are "static", that is "class" methods.) All the trigonometric functions use angles expressed in radians, not degrees or grads.

Immediately invoked function expressions can be used to avoid variable hoisting from within blocks, protecting against polluting the global environment and simultaneously allowing public access to methods while retaining privacy for variables defined within the function. In other words, it wraps functions and variables, keeping them out of the ...
The term "function prototype" is particularly used in the context of the programming languages C and C++ where placing forward declarations of functions in header files allows for splitting a program into translation units, i.e. into parts that a compiler can separately translate into object files, to be combined by a linker into an executable ...
