CEILING(A) returns the least integer greater than or equal to A.
Fortran 95 and later
Elemental function
RESULT = CEILING(A [, KIND])
| A | The type shall be REAL. |
| KIND | (Optional) An INTEGER initialization expression indicating the kind parameter of the result. |
The return value is of type INTEGER(KIND) if KIND is present and a default-kind INTEGER otherwise.
program test_ceiling
real :: x = 63.29
real :: y = -63.59
print *, ceiling(x) ! returns 64
print *, ceiling(y) ! returns -63
end program test_ceiling
