Removing decimal points

40
I'm wondering which data type will only give me the whole number and drop off the rest of the fraction?

For example if I have 3.14, but I just want 3, how can i get this done?

Convert the floating point number to an int.
int result = (int) 3.14;

You could also do it with Math.floor() or Math.ceil() or Math.round() or especially Math.rint(), depending in which way you want to cut off.

There are a number of API options for controlling output formatting. This will show you what you want.

some titorials:

{
double d = 3.43;
int x ;
double s;
s = x; // right
x = s; // wrong
x = (int)d; //write
x = d; // wrong
. // ???
. // ???
. // ???

}
