Alice supports four of the five

(Display Figure 1.)

Alice supports the first four operators shown in Figure 1.

Apparently Alice does not support the modulus operator.

However, the world has a function named Math.IEEERemainder that may serve the same purpose.

A bug in IEEERemainder function
Sometimes the function returns the correct answer and sometimes it returns the wrong answer. On the basis of a very limited amount of experimentation, it seems to return the correct answer for those cases where the correct answer is 0.
