SYNOPSIS
     FLOOR ([A=]a [,[KIND=]kind])

STANDARDS
     Fortran

DESCRIPTION
     The FLOOR intrinsic function returns the greatest integer less than or
     equal to a.  It accepts the following arguments:

     a         Must be of type real

     kind      An integer scalar value.  Must be a scalar integer
               initialization expression

     FLOOR is an elemental function.  The name of this intrinsic cannot be
     passed as an argument.

RETURN VALUES
     The result is an integer.  If kind is specified, the kind type
     parameter is that specified by kind.  If kind is not specified, the
     result is of type default integer.  The result has value equal to the
     greatest integer less than or equal to a.  The result is undefined if
     the target machine cannot represent this value in the default integer
     type.

EXAMPLES
     FLOOR(3.7) yields 3.

     FLOOR(-3.7) yields -4.
