Simple:
double d = 0.15682534735275272;
double trimD = ((int)(d * 100)) / 100.0;
This will output 0.15, and I think it's faster then wrking with Strings.
Of course, you can create a generic method that will trim your value to any decimal location you like.

looked a bit closer at your code, and you are right :-/
That will perform rounding to a certain number of d.p. and is quite cool :-)
