Q.  What's the best way to convert a float to an int?

A.	Use Math.round() like this

float f = 55.6;
int i = Math.round(f);	// Will be 56

This is the simplest way, but not the best:

int i = (float)f;

You can make your own round like this:

int i = (float)f + .5f;	// Homemade round, use read Math.round() to be clear

If you don't want to round you can also do:

int i = Math.ceil(f);
int i = Math.floor(f);
