WebMay 18, 2011 · Unfortunately, when casting a floating-point value to an integer in C, the value is rounded towards zero. This mean that if you have 339.999999, the result of the cast will be 339. To overcome this, you could add (or subtract) "0.5" from the value. In this case 339.99999 + 0.5 => 340.499999 => 340 (when converted to an int).
