Round in Java ME, e.g. in J2ME

The code below is method that shows how to
round a double to n decimals:

private double round(double num,int numDecim){
long p=1;
//next line – calculate pow(10,brDecim)
for(int i=0;i<numDecim;i++)p*=10;

return (double)(int)(p*num+0.5)/p;
}

You may use double p=1.0; or p*=10.0; instead.

All of the storage compartments tend to be a great size and truly assist keep every thing organized. The handles are a fantastic length and fit nicely over the actual shoulder; the tackle shoulder straps also stay place on my own arm, which is actually essential when you're having a baby. The handbag looks wonderful, as well. Not as well fancy, but not as well casual. (I have it in black) The material is soft (can't assume of a greater word) so it's simple to squeeze in to tight spaces - but yet it is sturdy. I have a Fleurville Lexi carry and I love it, as well, but that bag is actually type of inflexible. I believe this Skip*Hop can turn into my everyday tote. It's a bit big - so if you're not in to large totes this may well be superior as an over-night baby diaper tote.

Math.Pow is my own pow function(). double sum = numberToRound; double round = .5 / Math.Pow(10, precision+1); sum = (sum > 0) ? sum + round : sum - round; int temp=(int)((sum*Math.Pow(10,precision))); sum = (((double)temp)/Math.Pow(10,precision)); This will round not truncate. Math.Pow is my own pow function().

double sum = numberToRound;
double round = .5 / Math.Pow(10, precision+1);
sum = (sum > 0) ? sum + round : sum – round;
int temp=(int)((sum*Math.Pow(10,precision)));
sum = (((double)temp)/Math.Pow(10,precision));
