[Newbies] How to round a float?

[Chuck Hipschman]

7 / 8.0 roundTo 0.01 = 0.88  Aha! Thanks!

But:

100 * (1.05 raisedTo: 10) roundTo: 0.01 162.89000000000001

"162.88946267774418" "unrounded"
100 * (1.05 raisedTo: 15) roundTo: 0.01 207.89000000000001

 "207.8928179411367"  "unrounded"
 Bug, or me again :-)
