hello guy. i have a problem with ceiling and Floor method..i know that
Math.ceil(7.5) is == 8

but how can i do to Math.ceil (75) to become 80
or
 Math.ceil(125) to become 130...???

also to Math.floor(25) to become 20

ok guys! i will be waiting for ur reply!. bye

Watch this: you can chop-off with (int) too!

int theNumber = 10* (int)Math.ceil(oldNumber/10.0); // all data types

int theNumber = 10* (int)(oldNumber/10.0); // all data types


// You might combine these in a method like:
public static double roundNumber(double number, int digits, boolean roundUp)
{
double factor = Math.pow(10.0, digits); // digits=1, factor=10

if(roundUp)
    return factor*(int)Math.ceil(number/factor);

return factor*(int)(number/factor); // else
}
// I didn't try this out, but it should work!


Cheerz!
