I'd like to round at most 2 decimal places, but only if necessary.
Input:
10
1.7777777
9.1
Output:
10
1.78
9.1
How can I do this in JavaScript?

Use Math.round() :
Math.round(num * 100) / 100
Or to be more specific and to ensure things like 1.005 round correctly, use Number.EPSILON :
Math.round((num + Number.EPSILON) * 100) / 100
