ceiling(x), x REAL or a structure with REAL components |

ceiling (x) rounds the elements of the REAL variable x to the next integer in the positive direction, producing a vector, matrix, or array with the same shape as x. Example: Cmd> ceiling(vector(3.1416, -3.1416, 12)) (1) 4 -3 12 When x > 4503599627370495 or x < -4503599627370495, ceiling(x) is set to MISSING because of the impossibility of exact representation of integers beyond these limits. These limits may be different on some computers. When x is a structure consisting of REAL components, so is ceiling(x). If the i-th component of x is xi, the i-th component of ceiling(x) is ceiling(xi). See also topics floor(), round(), 'structures'.
