(int)15.9999 = 15
(int)15.4999 = 15
(int)15.5 = 15
(int)15.1 = 15
Real example: 99+99+99+99+98 = 494 / 500 = 0.988 * 100 = 98.8
(int)98.8 = 98
If you intend on rounding to the nearest integer (whole number) then adding 0.5 remedies this situation:
(int)(15.9999 + 0.5) = 16
(int)(15.4999 + 0.5) = 15
(int)(15.5 + 0.5) = 16
(int)(15.1 + 0.5) = 15
Real example: 99+99+99+99+98 = 494 / 500 = 0.988 * 100 = 98.8
(int)(98.8 + 0.5) = 99
Watch out for negative numbers!
