Math.floor()

syntax:

Math.floor(x)

where:

x - a number.

 

return:

number - the greatest number value that is not greater than the argument and is equal to a mathematical integer.

 

description:

If the argument is already an integer, the return value is the argument itself.

 

example:

//The floor of x is returned 

//in the following function:

function compute_floor(x)

{

   return Math.floor(x)

}

//If 6.78 is passed to compute_floor, 

//7 will be returned. If 89.1

//is passed, 90 will be returned.
