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

sqrt(x) returns the square roots of the elements of x, when x is a REAL scalar, vector, matrix or array. The result has the same shape as x. If any element of x is MISSING, so is the corresponding element of sqrt(x). If any element of x < 0, the corresonding element of sqrt(x) is MISSING. In both cases a warning message is printed. When x is a structure, all of whose non-structure components are REAL, sqrt(x) is a structure of the same shape and with the same component names as x, with each non-structure component transformed by sqrt(). See topic 'transformations' for more information on sqrt().
