Any sort of rounding like this, when you want to affect the number
itself (rather than just the display of the number) is handled by
1... Multiplying the number by 10^n (n = number of dec. places you want
to keep, in your case, 2).
2... Rounding to the nearest integer.
3... Dividing by 10^n (same n, of course).
