That's is actually what happends when you convert a float (or double) to an
int.

i just want to drop the decimal part.

Do like this,

float f = 234.33;
int i = (int) f; // i has value 234.

Thanks in advance.

you're welcome

Do like this,

float f = 234.33;
int i = (int) f; // i has value 234.

this is right if you want to drop.
Right conversion is made with Math.rint() or Math.round().
or you can do it by hand:

float f = 234.33;
int i = (int)(f + 0.5f);
//i has value 234

float f = 234.57;
int i = (int)(f + 0.5f);
//i has value 235;

Yes I agree. However, the original poster specifically asked for a decimal
drop. He/she (it?) also wanted the value converted to an int, in the case of
Math.rint() the returned value is a double so you'd need a conversion
anyway.
