SQRT function

Description

SQRT(x) returns the square root of the positive number x. SQRT(x)=x^(1/2). If the argument x of the function is negative, then the function returns an error (missing value).

The argument x can be a real number, a complex number, or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the SQRT function applied to all elements.

Example

SQRT(25) equals 5

SQRT(-9) returns an error (no value).
