     Big numbers can write using the below format in javascript.


     In javascript we can easy to convert any numbers to corespoinding hexadecimal, octal or binary value using toString() method.

     If you have many messages for delete from facebook, it is very difficult to select all the messages, because facebook don't have the option for select all the message at once and delete in a click. But we have the solution for this we will give a small script for selecting all the message at once and delete in a single click.

     The parseInt() function parses a string argument and returns an integer of the specified radix (the base in mathematical numeral systems).

     The parseFloat() function parses a string argument and returns a floating point number. parseFloat is a top-level function and is not associated with any object.

     parseFloat parses its argument, a string, and returns a floating point number. If it encounters a character other than a sign (+ or -), numeral (0-9), a decimal point, or an exponent, it returns the value up to that point and ignores that character and all succeeding characters. Leading and trailing spaces are allowed.

Naming Conventions for SQLite
     Each database, table, column, index, trigger, or view has a name by which it is identified
and almost always the name is supplied by the developer.The rules governing how a
valid identifier is formed in SQLite are set out in the next few sections.

Valid Characters
     An identifier name must begin with a letter or the underscore character, which may be
followed by a number of alphanumeric characters or underscores. No other characters
may be present.

   SQLite is not directly comparable to client/server SQL database engines such as MySQL, Oracle, PostgreSQL, or SQL Server since SQLite is trying to solve a different problem.

Client/server SQL database engines strive to implement a shared repository of enterprise data. They emphasis scalability, concurrency, centralization, and control. SQLite strives to provide local data storage for individual applications and devices. SQLite emphasizes economy, efficiency, reliability, independence, and simplicity.

     The toFixed() method formats a number using fixed-point notation.

digits
Optional. The number of digits to appear after the decimal point; this may be a value between 0 and 20, inclusive, and implementations may optionally support a larger range of values. If this argument is omitted, it is treated as 0.

Returns
A string representation of numObj that does not use exponential notation and has exactly digits digits after the decimal place. The number is rounded if necessary, and the fractional part is padded with zeros if necessary so that it has the specified length. If numObj is greater than 1e+21, this method simply calls Number.prototype.toString() and returns a string in exponential notation.

Throws

RangeError
If digits is too small or too large. Values between 0 and 20, inclusive, will not cause a RangeError. Implementations are allowed to support larger and smaller values as well.

TypeError
If this method is invoked on an object that is not a Number.

     The toPrecision() method returns a string representing the Number object to the specified precision.

     A string representing a Number object in fixed-point or exponential notation rounded to precision significant digits. See the discussion of rounding in the description of the Number.prototype.toFixed() method, which also applies to toPrecision().

     If the precision argument is omitted, behaves as Number.prototype.toString(). If the precision argument is a non-integer value, it is rounded to the nearest integer.
