    Summary: Rhino has high CPU usage and potential DoS when passing specific numbers to `toFixed()` function

    Details: When an application passed an attacker controlled float poing number into the `toFixed()` function, it might lead to high CPU consumption and a potential Denial of Service. Small numbers go through this call stack: `NativeNumber.numTo > DToA.JS_dtostr > DToA.JS_dtoa > DToA.pow5mult` where `pow5mult` attempts to raise `5` to a ridiculous power. Example code: `(4.47118444E-314).toFixed(2)`
