CEILING — Integer ceiling functionCEILING(A) returns the least integer greater than or equal to A.
RESULT = CEILING(A [, KIND])
| A | The type shall be REAL.
|
| KIND | (Optional) An INTEGER initialization
expression indicating the kind parameter of the result.
|
INTEGER(KIND) if KIND is present
and a default-kind INTEGER otherwise.
