Math.getNCube()

11/06/2002 in AS1 and Flash. 0 Comments

This function returns the number of components of an n-dimensional cube (known as an n-cube or measure polytope) as an array. For example If you need to know a cube’s number of components, then you would type Math.getNCube(3) and you’ll simply get the number components as the array “[8,12,6,1]“. The two examples after the code should give enough information about the usage of this function.

Math.isNatural()

07/06/2002 in AS1 and Flash. 0 Comments

This function simply detects if the input is a natural number.

Math.isNatural = function(_number){
   var isInteger =   (_number % 1 == 0)  
   var isPositive =     (_number >= 0)
   return isInteger && isPositive
}

usage:

// returns true
trace(Math.isNatural(13))
// returns false
trace(Math.isNatural(-4))
// returns false
trace(Math.isNatural(Math.PI))
