floor(3I)

NAME
     FLOOR - Returns the greatest integer less than or equal to its
     argument

SYNOPSIS
     FLOOR ([A=]a)

IMPLEMENTATION
     UNICOS, UNICOS/mk, and IRIX systems

STANDARDS
     Fortran 90

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

     a    Must be of type real

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

NOTES
     On UNICOS systems, both execution speed and the number of bits used in
     mathematical operations are affected when compiling with
     f90 -O fastint, which is the default setting.  For more information on
     this, see the CF90 Commands and Directives Reference Manual,
     publication SR-3901.

RETURN VALUES
     The result is a 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) has the value 3.  FLOOR(-3.7) has the value -4.
