FLOOR FLOOR Floor Function

Usage

Computes the floor of an n-dimensional array elementwise.  The
floor of a number is defined as the smallest integer that is
less than or equal to that number. The general syntax for its use
is

   y = floor(x)

where x is a multidimensional array of numerical type.  The floor 
function preserves the type of the argument.  So integer arguments 
are not modified, and float arrays return float arrays as 
outputs, and similarly for double arrays.  The floor function 
is not defined for complex types.
