Hello!

If you want to "truncate" it for example after 2 decimals, why not this:

float a = 3.2335998798;

float b = 100 * a; // 323.35...

int32 c = (int)b;

a = c/100;

Now if you simply want to display it you should consider using the right format for printf (or sprintf).
It's all in man printf.
