The round answers given below are simply aliases of your toFixed() method... Although, with your example toFixed returns 0.14 on Chrome. — Salketer, Aug 04 '14 at 12:00
@Dale jQuery is library of useful JavaScript functions, methods, wrappers etc. For the basic stuff one should still use plain JavaScript. No point wrapping one-liner in other one-liner. — Shadow The GPT Wizard, Aug 04 '14 at 12:34

You should first multiply the result by 10^(number of decimals), then round the number, than divide this number by 10^(number of decimals).

In this case:

Math.round((newCostDiff/2)*100) / 100;
