Is there a math symbol that stands for becomes?

Just curious because it would really work into a few problems I am doing

What is the context?
Barred arrow notation shows the result of applying a function to the object on the left of the arrow. An example would be:
$$x \mapsto x^2 + 4$$
which is read as "x is mapped to x squared plus 4."

How about $\Longrightarrow \text { or } \Rightarrow$ ?

Got any concrete example??

Yeah, show us what you want to use it for.
I put in another vote for when $f:X\to Y$, then for any $x\in X$,

$x\mapsto y$, where $y\in Y$.

This is for elements. Bob S's version may be better for statements. But if you show us an example, we can be sure that we mean what we mean.

I would go with the side arrow, although depending on what you're using it for, it may be an abuse of notation. I usually go with the style of arrow Bob S suggested, although I think it means "implies" if you're strictly adhering to convention.

The tilde symbol ~ can mean "becomes asymptotically equal to", e.g. $f(x)$ ~ $g(x) \Rightarrow \lim_{x \rightarrow \infty} \frac{f(x)}{g(x)} = 1$.
