The limit of 5 decimal places makes it a bit impractical for my use case:
While debugging, I often use fast numerical approximations to obtain out some number, that I know should somehow relate to some properties of the input, combined with some constants. But the precision is often less than 5 decimal places.
Example: The operator norm of some operation or some integral -- is it pi/4<i>inputsize? ln(2)</i>inputsize? sqrt(1/2)*inputsize?<p><a href="https://www.wolframalpha.com/" rel="nofollow">https://www.wolframalpha.com/</a> is really useful in that case
