ceiling(3I)

NAME
     CEILING - Returns the least integer greater than or equal to its
     argument

SYNOPSIS
     CEILING ([A=]a)

IMPLEMENTATION
     UNICOS, UNICOS/mk, and IRIX systems

STANDARDS
     Fortran 90

DESCRIPTION
     The CEILING intrinsic function returns the least integer greater than
     or equal to its argument.  It accepts the following argument:

     a    Must be of type real

     CEILING 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 type is a default integer.  The result has a value equal to
     the least integer greater than or equal to a.  The result is undefined
     if the system cannot represent this value in the default integer type.

EXAMPLES
     CEILING(3.7) has the value 4.  CEILING(-3.7) has the value -3.
