Parse Error for less than symbol in ng-bind braces

```
      span.credits-count--emphasis
        | {{ currentCredits < 0 ? '0' : currentCredits }} &nbsp;
```

```
Running "ngtemplates:App" (ngtemplates) task
Warning: Parse Error: < 0 ? '0' : currentCredits }}
```

Any way to bypass this error? Thanks!
