Declaration

Discussion
This method automatically coerces certain types to their equivalent integer values. The Boolean value true becomes 1.0 and false becomes 0.0. An integer becomes the equivalent floating-point number –– for example, 2 becomes 2.0. A string that contains a numerical value contains the equivalent floating-point value — for example, “123.4” becomes 123.4.
