If you want to round it, you have to write the following:
code:float a = 45.426;int b;b = a + 0.5;
This should work... BYE

I've learned that the reslt will be 45, but I've never tested it.
If you want to round it, you have to write the following:

As a complement to the post above, i can confirm that the value will be truncated, not rounded.
Indeed it will be set to 45. Because it just chops the fraction off of it.......

What will result from this:
int x;
float y;
y = 45.54525252552
x = y;
Will x be rounded to 46, or will the fraction just get chopped? And if it is chopped, how can I force it to round up if the fraction is greater than or equal to 1/2?
Also, if you want to make sure of a value being set to one side or other of an integer you can use
double floor(double)...rounds down
and
double ceil(double)...rounds up
from Math.h
