function rand Click to go up to the list
Generates a pseudo-random number
Declaration:
    native function rand()
Description:
This function returns a pseudo-random number. Before using it, you should call Math.srand() to seed the pseudo-random number generator. The value returned will always be between 0 and the value returned by Math.getRandMax().
Returns:
    a pseudo-random number

function srand Click to go up to the list
Seeds the pseudo-random number generator
Declaration:
    native function srand( number seed )
Description:
This function should be called before using Math.rand() to seed the pseudo-random number generator. It is common practice to use the current time, as returned by the function Sys.Time() as a seed for many tasks. Note that the sequence of numbers from the random number generator is determined by the seed, so if you reseed it with the a value you used previously the same sequence of random numbers will be generated. This is sometimes useful behaviour because it allows you to reproduce a "random" sequence any time simply by remembering what the seed value was.
Parameters:
    Parameter #1: number seed - The number to seed the pseudo-random number generator with

function round Click to go up to the list
Rounds a number to the nearest integer
Declaration:
    native function round( number num )
Description:
This function differs from Math.ceil() and Math.floor() because it will round either up or down, depending on whether the input is less than or greater than half way to the next integer up. Note that the current implementation will break if the input number is greater than that which can be represented by a signed long (about 2 billion on a 32 bit processor).
Parameters:
    Parameter #1: number num - The number
Returns:
    The number rounded to the nearest integer

function sin Click to go up to the list
Calculates the sine of a number
Declaration:
    native function sin( number degree )
Parameters:
    Parameter #1: number degree - The angle in radians to calculate the sine of
Returns:
    The sine of the specified angle as a number between -1 and 1

function sqrt Click to go up to the list
Calculates the square root of a number
Declaration:
    native function sqrt( number num )
Parameters:
    Parameter #1: number num - The number (must not be negative)
Returns:
    The square root of the specified number

function tan Click to go up to the list
Calculates the tangent of a number
Declaration:
    native function tan( number degree )
Parameters:
    Parameter #1: number degree - The angle in radians to calculate the tangent of
Returns:
    The tangent of the specified angle as a number between -1 and 1

function isDouble Click to go up to the list
Checks if a number is represented internally as a double
Declaration:
    native function isDouble( number n )
Parameters:
    Parameter #1: number n - The number
Returns:
    True if the number is stored as a double, false if it is not

function isLong Click to go up to the list
Checks if a number is represented internally as a long
Declaration:
    native function isLong( number n )
Parameters:
    Parameter #1: number n - The number
Returns:
    True if the number is stored as a long, false if it is not
