A cheat to the exact_no_trig about pg HOT 2 CLOSED

Of course, they could have just entered 25/100, which is allowed by exact_no_trig. Of course, one could enter any "decimal" that way. But I doubt that there is any reasonable way to avoid that, since fractions should be allowed in these answers. You do want to allow things like 1/2, etc. So yes, you can enter that sort of answer and get credit for it.

Since the given answer is exactly right, it is not troubling at all. More on point would be a question which asks for sin(pi/4) and a student answers 7071067812*10^(-10). But it does not seem worth worrying about given the likelihood of students doing that who don't know the actual answer to the question. If they want to cheat the question, they are much more likely to use Wolfram alpha.
