Operator Precedence
{{#include ../links.md}}
All operators in Rhai has a precedence indicating how tightly they bind.
A higher precedence binds more tightly than a lower precedence, so * and / binds before + and - etc.
When registering a custom operator, the operator's precedence must also be provided.
The following precedence table shows the built-in precedence of standard Rhai operators:
