The SQRT function uses the following argument: To understand the uses of the SQRT function, let’s consider a few examples: Suppose we wish to find the square root of the following numbers: The formula used would be =SQRT(reference). Sqrt [a b] is not automatically converted to Sqrt [a] Sqrt [b]. C library function - sqrt() - The C library function double sqrt(double x) returns the square root of x. The square root of a negative number does not exist among the set of real numbers. But, when I go to the documentation, I would really like to see what is the data type being returned.
