First example:
3*x^4 − 3.5*x^2 − 0.6 when x = −3.25 and x = 3.25;
−3*x^5 + 1.5*x^3 + 7*x when x = 1.7 and x = −1.7.

Second example:
the decimal representation for  (232)₅, (232)₁₆, (110011)₂, (123)₄, (123)₈, (D2B)₁₆:

If you want, you can change the value of "Round" (at the beginning its value is 4).
