### Boolean Operators ### Boolean Operators
UCG has the standard boolean operators: `&&` and `||`. Both of them short circuit and they require the expressions on each UCG has the standard boolean operators: `&&` and `||`. Both of them short
side to be boolean. circuit and they require the expressions on each side to be boolean.
``` ```
true && false == false; true && false == false;
false || true == true; false || true == true;
``` ```
In addition to the binary operators `&&` and `||` UCG also has the unary
operator `not` which reverses a boolean value.
```
not true == false;
not false == true;
```
