Maybe I did not get your question right. This is very elementary C. If you want to just truncate the decimal part of a floating point variable you just cast it to int: int firstint=(int)firstfloat; int secondint=(int)secondfloat;
If you want to have the nearest integer, this is what you need int firstint=(int)(firstfloat+0.5); int secondint=(int)(secondfloat+0.5);
This does not round to the nearest, because for the +0.5 trick to work, the rounding that occurs after must be downwards, like floor(), instead of towards zero, like a (int) cast.
(This is very elementary C too ;-)
