Cube root approximation is somewhat of a black art. Some implementations manipulate the exponent bits of the floating-point number; i.e. they arrive at an initial approximation by dividing the exponent by 3. Cubic equations, which are polynomial equations of the third degree (meaning the highest power of the unknown is 3) can always be solved for their three solutions in terms of cube roots and square roots (although simpler expressions only in terms of square roots exist for all three solutions, if at least one of them is a rational number). If two of the solutions are complex numbers, then all three
Cube (film series) the maze, while also trying to solve the mystery of what the cube is and why they are in it. However, the pressure of being in the Cube generally turns one of the prisoners into a homicidal maniac who preys on the others. "Cube Zero" was slightly different from the first two films in that it also dealt with the people on the outside of the Cube whose job it was to control the cube and oversee those within. A fourth film was rumored in March 2011, and a remake of the first film was announced in April 2015. In
