Quick Java Division fix

[Spardan]

Hi guys...

I'm doing static task allocation - need to divide a task into iterations.

I have a long, which is the total iterations, and want to divide by 3 for three nodes.

Problem is, how to round up/down to make sure I only get whole numbers?

Was thinking something like this:

long totalIterations = <a number>;

long chunk = totalIterations/3;

long chunk1 = chunk.roundUp();
long chunk2 = chunk.roundUp();
long chunk3 = totalIterations - (chunk1+chunk2);

So does anyone know of a method for rounding up (or down) a long with decimal places?

Thanks!

Goddamn I'm dumb...

Math.round, perhaps?

meh.


I'd been looking in the java.math package... it never occurred to me (ever!) that there was a Math object...

ah well... I live (barely) and learn (eventually)!

rounding is easily done using

return new Integer(long+0.5).intValue();

. Thats all the Math.round function does (logic been an int value just cuts the decimals off therefore 0.2+0.5 = 0, but 0.7+0.5 = 1).
