## `IsIntrinsic(S): MonStgElt -> Bool, Intrinsic`

Given a string $S$, return `true` if and only an intrinsic with the name $S$ exists in the current version of Magma. If the result is `true`, return also the actual intrinsic.

## `Example: Is Intrinsic (ex-c50516)`

We demonstrate the function `IsIntrinsic`.

```magma
> IsIntrinsic("ABCD");
false
> l, a := IsIntrinsic("Abs");
> l;
true
> a(-3);
3

```
