argument
SYNOPSISCEILING ([A=]a)
IMPLEMENTATION
UNICOS, UNICOS/mk, and IRIX systems
STANDARDS

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.
