Hi,
I have a question. Let $F|\mathbb{F}_q$ be algebraic function field and $P$ is a rational place of $F$. suppose $f \in F$ is regular at $P$. Is there any algorithm to evaluate the image of $f$ in the residue class field $\tilde{F}_p= O_p/P$?
I know Magma can do that, but I am trying to know how I can do it myself for specific example?
