Sometimes we want to express that two objects are equal up to a constant but there is no need to keep writing out the constant or constants. For example, often times the constant or constants involved in the derivation of a primitive of a function plays or play a role unimportant.
I wonder if there is a convenient, established notation for such a matter. I thought of using modular notation. But using that does not simplify because I still have to mention "modulo-what".
If possible, some variants of the equality sign are preferable. For instance, if the constant of proportionality is unimportant then it may be suppressed by using $\propto.$ In this sense I mean by saying that some variants of the equality sign are preferable.

Apparently there is no standard notation. I have seen $\propto$ used in the additive context as well as the multiplicative, leaving it to the reader to overcome the abuse of notation.
