Consider a typical function from mathematics:f(x) = 2x + 5In mathematics, the symbol 'x' is a placeholder, and when you run the function for a value, you "plug in" the value in place of x. This function will always return an Int8 regardless of the types of x and y. Stores either value true or false. If for some reason you need to get the square root of a negative number (i.e. Let’s take another example, the ABS() function — it should return the #NUM! The type attributes for the return value are also copied from the first argument, except in the case of DECIMAL, when the second argument is a constant value. The square root of a negative real numeric constant returns a purely imaginary value and signals real_to_complex.Otherwise the sqrt(x) function tries to simplify x^(1/2).If no simplifications can be made, the expression x^(1/2) is returned. 5. double.
