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

floor(x) rounds the elements of the REAL variable x to the next integer in the negative direction, producing a vector, matrix, or array with the same shape as x. Example: Cmd> floor(vector(3.1416, -3.1416, 12)) (1) 3 -4 12 When x > 4503599627370495 or x < -4503599627370495, floor(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. If x is a structure, so is floor(x). If xi is the i-th component of x, the i-th component of floor(x) is floor(xi). See also topics ceiling(), round(), 'structures'.
