The string is converted to a number value. JavaScript attempts to convert the string numeric literal to a Number type value. First, a mathematical value is derived from the string numeric literal. Next, this value is rounded to nearest Number type value. Boolean
Values are cast to strings like the following: [59] Strings are left as-is; Numbers are converted to their string representation; Arrays have their elements cast to strings after which they are joined by commas (,) Other objects are converted to the string [object Object] where Object is the name of the constructor of the object
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
For example, Java's numeric types are primitive, while classes are user-defined. A value of an atomic type is a single data item that cannot be broken into component parts. A value of a composite type or aggregate type is a collection of data items that can be accessed individually. [6]
There are a number of new functions introduced in this example. pos returns the current value of &pos. It may not be immediately obvious why one would need this function and not simply use the value of &pos directly; the reason is that &pos is a variable and thus cannot take on the value &fail, which the procedure pos can.
The stropping feature allows the use of any name for variables or functions, even when the names are reserved words for keywords. An example of stropping is the ability to define a variable named if, without clashing with the keyword if. Nim's implementation of this is achieved via backticks, allowing any reserved word to be used as an identifier.

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 ...
