Maybe this question is stupid, but how would people take care of, say, cos(42) and log2(3) in Verilog? Thanks.

Use a look up table, or CORDIC

If you have ample resources available (if area is not your top concern right now), you can also use ALTFP_SINCOS and ALTFP_LOG megafunctions.

Well, use CORDIC to calculate cos() is straight forward. But what is the procedure to do log2(3) in CORDIC?
