ceilsqrtx2x

ceilsqrtx2x is a mathematical function that calculates the ceiling of the square root of a given input, then multiplies the result by two. The function takes a single non-negative numerical input. First, the square root of the input is computed. Next, the ceiling function is applied to this square root. The ceiling function, denoted by the 'ceil' operator, rounds any fractional part of a number up to the nearest whole number. Finally, this rounded-up value is multiplied by two. For example, if the input is 10, the square root is approximately 3.162. The ceiling of 3.162 is 4. Multiplying 4 by 2 gives a result of 8. If the input is a perfect square, such as 9, the square root is exactly 3. The ceiling of 3 is 3, and multiplying by 2 results in 6. The function is defined for non-negative real numbers. Its output is always an even integer.
